Dual-screen Independent Display Smart Query Board, WF-K3288, AndroidSBC, San Antonio

TL;DR: Dual-screen Independent Display Smart Query Board

AndroidSBC release: twelve-model WF-K self-service query terminal motherboard family opens for volume orders serving San Antonio, United States. The WF-K3288 self-service query terminal Android motherboard spans the legacy query terminal refresh with hall display and eleven sister models in the WF-K series, all built on the RK3288 quad-core ARM Cortex-A17 1.8GHz SoC with the ARM Mali-T764 GPU, 1080p HDMI plus LVDS, and Android 10 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-K family from the Longgang source factory in Shenzhen to San Antonio and United States importers who run hospital information points, bank branch lobbies, government service halls, mall directory stations, airport concourses and outdoor query cabinets.

About AndroidSBC and the Self-Service Query Terminal Android Motherboard Family

Wanlin Manufacturing Group builds boards and nothing else, which is why the WF-K query terminal line is sold factory direct through AndroidSBC. Twelve models cover hospital, bank, government, retail, transport and outdoor query duty, and each one leaves the Longgang line in Shenzhen with the same peripheral driver bundle for San Antonio integrators. The factory ships to United States on a factory-direct basis, with the driver SDK, compliance files and mounting drawings bundled into the same carton as the boards.

WF-K3288 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3288 (legacy query terminal refresh with hall display) maintains its 4K HDMI output plus capacitive touch sampling while running the burn-in test loop, a configuration that competing single-platform boards cannot sustain at 60fps. For United States importers sourcing the WF-K family, the WF-K3288-A variant is the typical configuration for the installed-base query terminal refresh use case, with a sustained weekly capacity of 5000 pcs/wk.

Challenges in Sourcing Self-Service Query Terminal Android Motherboards for United States Buyers

Sourcing a self-service query terminal board for United States is not only a chip question. A San Antonio integrator has to align the touch stack, the printer and scanner drivers, the enclosure cut-outs and the compliance file set before a single unit reaches the field.

Compliance and logistics compound each other. Boards for San Antonio move through Port of Los Angeles, and any mismatch between the FCC / UL documents and the FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing route applied in United States surfaces at exactly the wrong moment. AndroidSBC answers this with a single BOM per lot, so a San Antonio order of 1400 units carries the same silicon and firmware as the pilot batch for United States.

Competitive Comparison: WF-K3288 vs Competing Self-Service Query Terminal Android Boards

The comparison below reflects the configurations AndroidSBC ships to San Antonio against the typical competing query board offered in United States.

• Platform breadth: twelve models on eight chips (RK3588, RK3568, RK3566, RK3288, RK3399, A133, H618, T527), so {city} integrators can move between tiers without changing driver stack or mounting pattern.
• Bundled integration: touch, printer, scanner, card reader, camera and voice driver SDK ships in the carton; competing query boards sold to {city} usually ship a board only.
• Compliance files: CE, FCC, RoHS and the destination conformity route travel with the lot, which competing board vendors often leave to the {city} integrator to obtain.
• Long-term supply: one fixed BOM per production lot and a seven-year firmware window, against the frequent silicon swaps seen on competing query boards reaching {city}.

Global Self-Service Query Terminal / Information Kiosk Market Trends

Information access is being treated as infrastructure in United States, and that changes what is procured. Instead of one-off kiosks, San Antonio operators specify the legacy query terminal refresh with hall display as a standard unit to be repeated across a whole estate on the same firmware.

• Volume shift to board-level sourcing: more integrators now buy the motherboard rather than the finished kiosk, which is why the WF-K3288 and WF-K1330 tiers ship in board form with the enclosure left to the local partner.
• Dual-screen becomes the default: hall display plus touch query on one board is replacing two separate devices, and the WF-K1330 and WF-K1331 configurations address that pattern directly.
• Longer service life expectations: operators now plan five to seven years per query terminal, which favours a fixed BOM such as the WF-K1331 over boards that re-spin silicon between lots.

What this means for San Antonio is that the query board is no longer a disposable line item. It is the component that determines whether United States deployments can be extended rather than rebuilt.

Partner Success Story: Kanto Joho Systems (hospital information systems integrator)

The Kanto Joho Systems case in the Japan healthcare segment is a working example of how the WF-K family from AndroidSBC supports San Antonio integrators. Kanto Joho Systems installed 1400 query terminal boards across hospital information counters.

• OEM relationship: AndroidSBC private-label SKU shipped with Kanto Joho Systems branding and CE / FCC / RoHS files bundled.
• Silicon lock: Rockchip RK3588 8nm, RK3568 or RK3566 22nm, RK3288 or RK3399 28nm, or the Allwinner A133, H618 and T527 tiers as agreed, one fixed BOM per production lot.
• Peripheral driver SDK: bundled into the source-factory shipment, covering capacitive touch, thermal printer, receipt printer, document scanner, A4 printer, barcode scanner, QR code, NFC, RFID, card reader, ID reader, face recognition, voice module, speaker amplifier and microphone.
• Unattended-operation tools: hardware watchdog, RTC, scheduled power cycling, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback bundled.
• Compliance paperwork: CE / FCC / RoHS plus FCC / UL conformity, all bundled into the Shenzhen source-factory shipment.

Kanto Joho Systems General Manager for Japan Healthcare noted: Kanto Joho Systems specified silent touch response and precise formatting, and the WF-K board met both tests on the first lot of 1400 units delivered to San Antonio.

Field Report: installed-base query terminal refresh at a social security service hall

LONGGANG, Shenzhen, September 22, 2026 - Lai Feng, AndroidSBC field desk. The WF-K3288 lot was soak-tested with the hall display and the touch panel running from one board, the configuration most United States projects specify. The WF-K3288 self-service query terminal Android motherboard order for San Antonio, United States cleared the burn-in station on schedule and is en route via the Los Angeles - Shanghai lane.

The WF-K3288 legacy query terminal refresh with hall display production lot includes the WF-K3288-A variant as the typical configuration, with touch panel, thermal printer and document scanner driver SDK plus staged OTA management bundled into the source-factory shipment. For United States integrators, the FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing paperwork is bundled.

Filed by Lai Feng, AndroidSBC field desk, LONGGANG, Shenzhen. US hospital networks and bank branch estates usually refresh self-service query terminals site by site, so boards arrive with a fixed screen count and mounting pattern per branch.

WF-K3288 Application Scenarios

The WF-K3288 legacy query terminal refresh with hall display sits inside a twelve-variant WF-K self-service query terminal Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-K3288-A configuration is the typical build for the installed-base query terminal refresh use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.

• Hospital and clinic information points: the WF-K3288 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in San Antonio.
• Bank and financial branch lobbies: touch query plus counter display from one board, with card reader and ID reader integrated for account and product lookups.
• Government service halls: the WF-K6180 runs tax, social security and real estate information lookup, with printing available on the same board.
• Shopping mall directories: the WF-K5270 serves mall directory and wayfinding lookup, with the advertising screen running an independent content loop.
• Airport and train station concourses: high-brightness information query where the WF-K8800 has to stay readable under strong ambient light.
• Retail and pharmacy price or product lookup: compact stations where the WF-K8801 fits a narrow counter without structural work.
• Outdoor and unheated information cabinets: the industrial tier holds the wide temperature window and 7x24 duty cycle for street-level query points.
• Multi-language public information points: on-screen lookup in more than one language from a single board, with voice assistance where the venue requires it.
• Retrofit programmes in San Antonio: the same board re-uses the existing enclosure, panel and mounting pattern so an installed estate can be upgraded board by board.

Partnership Models for San Antonio Buyers

The partnership structure offered to San Antonio buyers is deliberately flexible: United States integrators can take the board alone, take it with the driver stack, or take it as a private-label programme.

• Distribution track: the partner buys the WF-K board against a published price list, keeps its own stock, and AndroidSBC supplies the driver SDK and compliance files with each lot.
• Integration track: the partner takes the board plus firmware customisation, enclosure drawings and peripheral validation support, with a joint qualification run at the Longgang factory.
• Private-label track: the WF-K board ships under the partner brand with customised boot logo, packaging and documentation, on a fixed BOM held for the length of the agreement.

Whatever track a San Antonio partner selects, the underlying board, firmware baseline and compliance files are identical, which keeps United States conversations about commercial terms rather than technical risk.

Frequently Asked Questions

Does the WF-K self-service query terminal Android motherboard family support a legacy query terminal refresh with hall display?

Answer: Yes, and it is qualified on the same production line as the rest of the family. The legacy query terminal refresh with hall display runs on the WF-K baseline image that United States buyers receive, so there is no separate integration project.

What is the real difference between the RK3288 tier and the other silicon tiers in the WF-K family?

Answer: The RK3288 tier sits at a specific point on the price-versus-headroom curve. Below it the boards suit single-screen information lookup; above it they support dual-screen independent display and heavier video work, and AndroidSBC documents that mapping for San Antonio buyers.

Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for United States?

Answer: Yes. Compliance files for United States are bundled into the source-factory shipment to San Antonio, and AndroidSBC provides the underlying test reports as well as the certificates on request.

What are the MOQ and lead time for a first order of the WF-K self-service query terminal family?

Answer: For San Antonio the entry MOQ is low enough to validate one site before committing to an estate, with 1-3 day samples and a 15-30 day first bulk lead time for United States.

Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?

Answer: Yes. Custom ROM work on the WF-K family is scoped per San Antonio project rather than sold as a generic service, which keeps the United States deliverable tied to a specific deployment.

How are software updates and long-term support handled on the WF-K family?

Answer: Software updates on the WF-K family are staged rather than immediate, with rollback available at each step, which matters when a San Antonio estate is live and United States sites cannot tolerate an unplanned outage.

Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?

Answer: Yes. AndroidSBC regularly ships the WF-K family into United States fulfilment centres on behalf of San Antonio sellers, handling the labelling and carton marking at the source factory.

How are RMA and DOA replacements handled on the WF-K self-service query terminal family?

Answer: RMA and DOA units are handled against the production lot, since every WF-K board is logged against its firmware revision and burn-in result before it leaves Shenzhen. San Antonio partners report against the lot number and AndroidSBC matches it to the rig log.
