Ubuntu Query Terminal Board, WF-K3600, AndroidSBC, San Antonio

TL;DR: Ubuntu Query Terminal Board

AndroidSBC reliability desk: query terminal boards clear a 72-hour continuous touch soak test serving San Antonio, United States. The WF-K3600 self-service query terminal Android motherboard spans the dual-screen query terminal with independent display and eleven sister models in the WF-K series, all built on the RK3568 quad-core ARM Cortex-A55 2.0GHz 64-bit SoC with the ARM Mali-G52 2EE GPU, dual 1080p independent output, LVDS plus HDMI, and Android 11 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. Every model is validated on the same burn-in rig in Longgang before it is packed for United States, and the same rig logs are available on request.

WF-K3600 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3600 (dual-screen query terminal with independent 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-K3600-A variant is the typical configuration for the dual-screen bank branch query rollout 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. For United States buyers the effect is that a 94200-unit order for San Antonio repeats identically the 8th time it is placed, down to the firmware revision.

Competitive Comparison: WF-K3600 vs Competing Self-Service Query Terminal Android Boards

For a San Antonio project the comparison is not a single chip benchmark. It is what the board carries into United States deployment as standard.

• 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

Self-service query terminals are moving from a specialist niche into standard public infrastructure, and United States is part of that shift. Demand for the dual-screen query terminal with independent display is being pulled by service halls that want to shorten front-desk queues and by operators in San Antonio who need the same answer available outside staffed hours.

• Volume shift to board-level sourcing: more integrators now buy the motherboard rather than the finished kiosk, which is why the WF-K3600 and WF-K6180 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-K6180 and WF-K5270 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-K5270 over boards that re-spin silicon between lots.

For San Antonio the opportunity sits in service coverage: operators in United States are adding information points faster than they are adding staff, and that gap is what the query terminal fills.

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

A Kanto Joho Systems deployment in the Japan healthcare segment illustrates how the WF-K query board family supports San Antonio integrators. Kanto Joho Systems installed 94200 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 94200 units delivered to San Antonio.

Field Report: dual-screen query terminal rollout at a city bank branch network

NANSHAN, Shenzhen, September 22, 2026 - Huan Xi, AndroidSBC field desk. The WF-K3600 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-K3600 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-K3600 dual-screen query terminal with independent display production lot includes the WF-K3600-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 Huan Xi, AndroidSBC field desk, NANSHAN, 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-K3600 Application Scenarios

The WF-K3600 dual-screen query terminal with independent 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-K3600-A configuration is the typical build for the dual-screen bank branch query rollout use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.

• Hospital and clinic information points: the WF-K3600 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-K3602 runs tax, social security and real estate information lookup, with printing available on the same board.
• Shopping mall directories: the WF-K3566 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-K3288 has to stay readable under strong ambient light.
• Retail and pharmacy price or product lookup: compact stations where the WF-K3399 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

Three partnership tracks serve the United States market, and San Antonio integrators can move between them as their own capability and volume change.

• 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.

The tracks are not exclusive of each other, and San Antonio partners commonly run distribution on one product line and private label on another for the same United States customer base.

Frequently Asked Questions

Does the WF-K self-service query terminal Android motherboard family support a dual-screen query terminal with independent display?

Answer: Yes, and it is qualified on the same production line as the rest of the family. The dual-screen query terminal with independent 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 RK3568 tier and the other silicon tiers in the WF-K family?

Answer: The RK3568 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: The first order MOQ on the WF-K family is set for pilot runs rather than container loads. San Antonio buyers can start small, then scale once United States field data is in hand, with 15-30 day bulk lead times.

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.
