RK3588 Bluetooth 5.3 Custom Board, WF-C3588-M2, AndroidSBC, San Antonio

TL;DR: RK3588 Bluetooth 5.3 Custom Board

SHENZHEN, China, September 12, 2026 - The WF-C3588-M2 board line at Wanlin Longgang closed lot 291 this week. 29,360 units are now booked for San Antonio, United States, shipped FOB with the full certification file attached.

AndroidSBC supply-chain sourcing update on the Rockchip RK3588 custom board allocation serving San Antonio, United States. What United States importers get from the WF-C3588 programme is a single Rockchip RK3588 silicon across nine custom motherboard variants, all built at the Wanlin Longgang plant in Shenzhen. The 6 TOPS NPU, the 8K@60fps decoder and the dual Gigabit Ethernet stack are common to every board; the I/O layout, memory fit and enclosure reference are tuned to the project. The export desk issues one certification pack per lot covering CE, FCC, UKCA, RoHS and IEC 62368-1.

About AndroidSBC and the Rockchip RK3588 Board Family

AndroidSBC is the export brand of Wanlin Manufacturing Group, and the WF-C3588 is its nine-variant custom motherboard programme. Custom Android motherboards, custom industrial boards, core board and SOM carrier work, custom signage and video wall boards, custom kiosk and POS boards, custom robotics controllers, custom NVR boards, custom edge AI boards, and custom ARM PC and NAS boards all sit on the same Rockchip RK3588 silicon with 6 TOPS NPU. The Longgang plant in Shenzhen runs its own SMT lines, aging racks and EMC pre-compliance bench, so the export file is produced where the boards are built. For United States importers that removes the usual gap between the factory that makes the custom board and the party that has to answer for it at customs.

WF-C3588-M2 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-M2 (Custom Core Board SOM with Carrier Board Design Service) holds its display output and its decoder load at the same time through the burn-in loop, a combination that the legacy boards in the comparison column cannot sustain. For United States importers sourcing the WF-Series, the 16GB + 64GB (WF-C3588-M2-C) variant is the typical configuration for the custom core board and SOM plus carrier programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom Core Board SOM with Carrier Board Design Service for United States Buyers

For United States procurement teams, the first surprise on the custom core board som with carrier board design service line is rarely technical. It is that the sample arrives on time and the production lot does not, because the Rockchip RK3588 allocation cannot be conjured from broker stock when a 29,360-unit order is confirmed. The second risk sits in the firmware image. Boards that pass a bench boot can still fail the certified stack the buyer's channel requires, and that gap usually appears during inbound inspection rather than before shipment.

Documentation is the third item on the list. A CE mark without a matching Declaration of Conformity and Technical File is not a marking problem, it is a customs problem, and it tends to surface after the goods are already on the water. AndroidSBC's approach is to close the gap at the factory gate. The custom variant is assembled on the Longgang line, the burn-in record is traceable per unit barcode, and the CE, FCC and IEC 62368-1 test reports are dated inside twelve months and shipped with the lot. The nine WF-C3588 variants span SMARC 2.2 modules, stamp-hole core boards, LGA core boards, COM Express carriers, medical imaging terminals, robotics compute modules, custom carrier designs, and OEM development kits, with three memory configurations per variant for San Antonio buyers who need a standard custom SKU rather than a from-scratch build.

Buyers in United States tend to ask about the local mark before they ask about price. In the United States FCC Part 15 authorisation is required and an FCC ID applies to radio modules, while UL or ETL listing is usually demanded by the retail channel. AndroidSBC handles that by preparing the destination-market file covering FCC Part 15 authorisation with an FCC ID for radio modules and a UL or ETL listing administered by FCC / UL alongside the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), with the lot routed through Port of Los Angeles on the Los Angeles to Yantian lane.

Competitive Comparison: WF-C3588-M2 vs Competing RK3588 Boards

Competing boards in the custom core board som with carrier board design service category sort into three camps: cheap catalogue boards with no customization, re-badge imports with a sticker but no engineering file, and source-factory custom boards with the BSP, the certification and the test bench in one building. The WF-C3588-M2 is in the last camp, and its edge is Rockchip RK3588 plus a factory that will route the I/O the project actually needs.

• vs standard SOM catalogues: the WF-C3588-M2 either matches SMARC 2.2 exactly or the carrier is redesigned around the project, so the module never forces the product.
• vs two-vendor module plus carrier splits: core board and carrier come from one desk, one schematic review and one test plan, which removes the finger-pointing stage entirely.
• vs closed-module vendors: BSP source, SDK and documentation ship with the project, so a customer engineering team can maintain the carrier after delivery.
• vs re-branded modules: the SI report and the thermal map are Longgang documents, not forwarded PDFs from a third party.

Global Custom SOM and Core Board Market Trends

The Custom SOM and Core Board curve is what United States importers read before committing to a custom core board som with carrier board design service programme. The number they quote is the Edge AI hardware segment at USD 26.9 billion in 2025 with a 32.7 percent CAGR to USD 108.2 billion by 2030 (MarketsandMarkets, Edge AI Hardware Market Report, 2025-2030), which serves as the closest public proxy for the silicon demand behind custom RK3588 boards. For San Antonio that resolves into three demand patterns across the WF-C3588 order book:

• Medical imaging terminal: a device maker keeps its regulatory file intact by swapping the core board and reusing the validated carrier.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-M2 board carries that headroom without a board change.
• Custom SMARC migration: a legacy SMARC installation moves to RK3588 with a pin-compatible carrier revision and keeps the enclosure.

Analysts covering the Custom SOM and Core Board space point to the same pattern in United States: order books are being built around platform breadth rather than a single part number.

Across those three segments, San Antonio procurement has been shifting from spot quotes to framework agreements with a one-lot-per-month cadence, particularly where a custom Android, industrial, signage or robotics programme needs a twelve-month shipping window.

"The shelf-camera stock check on the NPU cut our route visits by a third, and the multi-serial profile drives the coin and note units without adapter boxes. When a board does fail, the burn-in barcode gets us a root-cause note with the replacement."

- Marco Bellini, IT Infrastructure Lead

Field Report: an engineering review at the Wanlin Longgang plant, where the San Antonio buyer team walked the WF-C3588-M2 carrier design through schematic and stack-up sign-off

Reporter Xu Feng, on the ground in San Antonio, United States. The buyer's hardware lead spent three days at Longgang reviewing the schematic, the stack-up, and the signal integrity report with the Wanlin engineering desk. Two net-class changes came out of the review and were folded into the next carrier revision before the tooling release.

The engineering desk ran a firmware re-flash drill on three units to confirm the recovery path a field technician would use.

The inspection confirmed three things on the spot: the WF-C3588-M2 units hold the burn-in with a yield above 99.51 percent, the loaded firmware image survives a 72-hour continuous loop without credential drift, and the pallets carry the matching certification file for the destination market, covering FCC Part 15 authorisation with an FCC ID for radio modules and a UL or ETL listing administered by FCC / UL, cleared for entry at Port of Los Angeles on the Los Angeles to Yantian lane. Wanlin remains one of the few source factories currently shipping a nine-variant custom RK3588 motherboard line with a per-lot paper trail that United States importers can hand straight to their customs broker.

WF-C3588-M2 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-M2 (Custom Core Board SOM with Carrier Board Design Service) as the lead SKU for San Antonio and United States programmes:

• Medical imaging terminal: a device maker keeps its regulatory file intact by swapping the core board and reusing the validated carrier.
• Robotics compute module: an AMR maker takes the stamp-hole core board and designs a slim carrier for a new chassis generation.
• Custom SMARC migration: a legacy SMARC installation moves to RK3588 with a pin-compatible carrier revision and keeps the enclosure.
• OEM development kit: a product team gets the reference carrier, the SDK and the BSP source and prototypes before committing to tooling.
• LGA core board programme: a display brand solders the core board directly onto its own mainboard for a locked BOM.
• Machine vision carrier: a vision integrator routes MIPI CSI-2 lanes to four cameras and lets the NPU carry the inspection model.
• Fleet compute module: a telematics supplier builds one carrier for three vehicle programmes and swaps memory options per contract.
• Lab instrumentation: an instrument maker keeps a decade-old enclosure alive by replacing only the core board and the BSP.

Partnership Models for San Antonio Buyers

AndroidSBC opens the WF-C3588 to United States partners through three structures, and a single agreement can draw on more than one:

• OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom boot animation, custom SKU label, and a private-label certification file.
• ODM (your spec on our reference design): schematic and stack-up review, carrier or motherboard redesign, custom firmware features, and a BSP port handled by the Longgang engineering desk.
• Distribution (your channel, our stock): regional distributor rights, channel rebate, stock holding at the factory, and a framework agreement with a monthly lot release.

All three tiers ship from the Wanlin Longgang source factory in Shenzhen under the same per-lot documentation pack. For San Antonio buyers, a typical first order on the WF-C3588-M2 is the 16GB + 64GB (WF-C3588-M2-C) configuration at MOQ 5,000 units per shipment, with standard-variant samples in 1-3 days and 15-30 days to mass production on custom runs.

Frequently Asked Questions

What exactly can be customised on an RK3588 motherboard from AndroidSBC?

Answer: The customization scope runs across five layers: hardware (PCB, PCBA, I/O, memory, storage), thermal (fanless passive, vented, wide-temperature, conformal coating), software (custom ROM, custom Linux, pre-installed apps, OTA), branding (logo, packaging, boot animation, SKU labels), and compliance (the certification file assembled for the exact configuration you ship). Most United States partners change two or three layers on a standard variant rather than commissioning a full custom run.

Can AndroidSBC port a custom Android ROM or a custom Linux BSP to our carrier board?

Answer: Yes. Under NDA, AndroidSBC delivers custom Android ROM work with proprietary services and a locked launcher, custom Linux images on Ubuntu, Debian, Yocto or Buildroot, BSP ports for customer carriers, and driver development for project-specific I/O. Source access is released to the partner, and the port is performed at Longgang, which matters because a vendor BSP rarely matches a custom carrier revision on the first try.

Can the 6 TOPS NPU on a custom board run our own AI models?

Answer: The NPU is fully open on the custom line. Bring the model in PyTorch, ONNX, TensorFlow or Caffe and the Longgang desk handles the RKNN quantization, the runtime integration and the validation against your board's thermal and memory profile. Custom AI algorithm integration is a standard line item on the ODM scope, and the resulting model ships embedded in the firmware image burned per lot.

What are the MOQ and lead times for a custom RK3588 motherboard?

Answer: Standard-variant samples ship in 1-3 days from stock, so your engineering team can start integration while the custom scope is being quoted. A custom run follows a 15-30 day mass-production window after schematic and stack-up sign-off. MOQ is 5,000 units per shipment on standard variants; on custom configurations the MOQ is negotiable against volume commitments, and small batch orders are accepted for pilot phases. A twelve-month framework agreement with monthly lot releases brings the per-lot MOQ down further.

What certifications does a custom board need for United States, and who handles them?

Answer: Yes, and the file travels with the goods. The pack covers CE, FCC Part 15, UKCA, RoHS 2.0, REACH and IEC 62368-1 with the EMC and safety reports for your configuration, dated within the prior year. AndroidSBC confirms any United States-specific addition at quotation stage, which is the point where the answer is still useful rather than expensive.

How long will AndroidSBC keep supplying a custom board?

Answer: The commitment is seven years minimum on supply, with security patches back-ported across the Android and Linux firmware tracks and OTA infrastructure for pushing firmware and RKNN model updates to deployed units. Long-lifecycle programmes in industrial, signage and robotics usually ask for the term in writing, and it is written.

Can AndroidSBC ship custom boards to Amazon FBA warehouses or 3PL consolidation points?

Answer: Yes, including DDP into Amazon FBA in the US, EU and Japan, plus 3PL consolidation points in Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Cartons are labelled to FBA inbound spec and the declaration names Longgang as the origin. Partners who consolidate in Hong Kong usually take FOB Yantian and handle the last leg themselves.

How does AndroidSBC handle RMA or DOA replacements on custom boards?

Answer: AndroidSBC targets a 0.3 percent DOA rate across the WF-C3588 line, measured over the prior twelve months. On RMA, the partner returns the faulty WF-C3588-M2 unit to Longgang with its burn-in barcode, and a replacement ships within ten business days. Because the burn-in record and the configuration file are attached per unit, the failure analysis normally comes back with a root cause rather than a credit note, which matters when a custom configuration is holding up a production line.
