Query All-In-One Board China Factory, WF-K3600, AndroidSBC, Houston

TL;DR: Query All-In-One Board China Factory

AndroidSBC export desk: OEM, ODM and distribution tracks open on the WF-K self-service query board family serving Houston, 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 Houston 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

AndroidSBC manufactures the WF-K self-service query terminal Android motherboard family at the Wanlin Manufacturing Group plant in Longgang, Shenzhen. For United States buyers the series is deliberately broad: entry A133 boards for simple lookup stations, RK3568 workhorses for dual-screen work, and RK3588 parts where Houston projects need 8K or AI acceleration. The plant holds a standing allocation of LPDDR4X and eMMC for the WF-K line, which is how Houston projects keep their lead times stable across quarters.

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

Procurement teams in United States usually compare query terminal boards on price first, then find that integrating three vendors for touch, printing and identity peripherals costs more than the difference between a cheap board and the right one for Houston.

Compliance is the second filter. Houston buyers need a board whose FCC / UL file set matches the FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing route used in United States, which is the point where unbranded board suppliers usually drop out. For the 5th consecutive quarter, AndroidSBC has held the Houston allocation against one fixed BOM, which is why a 163500-unit programme can be dated rather than estimated.

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

Against the query boards usually quoted in United States, the WF-K board is positioned on integration completeness rather than on a single performance number for Houston.

• 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

Public-facing information lookup is now measured as a service-level question, not a hardware line item. United States procurement increasingly specifies the dual-screen query terminal with independent display as part of a wider access programme, which pushes Houston integrators towards boards that can be re-deployed across sites.

• 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-K3399 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-K3399 and WF-K1330 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-K1330 over boards that re-spin silicon between lots.

The direction of travel for Houston is towards fewer board variants deployed across more sites, which is exactly the configuration the WF-K series was built around for United States.

Partner Success Story: Northline Information Flow Group (multi-site service network operator)

The Northline Information Flow Group case in the North America service networks segment is a working example of how the WF-K family from AndroidSBC supports Houston integrators. Northline Information Flow Group retrofitted 163500 query terminals onto existing kiosk housings.

• OEM relationship: AndroidSBC private-label SKU shipped with Northline Information Flow Group 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.

As Northline Information Flow Group VP Service Operations for North America Service Networks put it: Northline Information Flow Group kept the cabinets and changed the boards, since the WF-K matched the mounting pattern and the LVDS panel already present, so 163500 units were upgraded in Houston without touching the enclosures.

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

NANSHAN, Shenzhen, September 22, 2026 - Lin Yao, AndroidSBC field desk. Field returns on the WF-K3600 lot were monitored per station, which is how United States integrators trace a fault back to a specific production run. The WF-K3600 self-service query terminal Android motherboard order for Houston, 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 Lin Yao, 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 Houston.
• 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-K1331 runs tax, social security and real estate information lookup, with printing available on the same board.
• Shopping mall directories: the WF-K6180 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-K5270 has to stay readable under strong ambient light.
• Retail and pharmacy price or product lookup: compact stations where the WF-K8800 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 Houston: 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 Houston Buyers

AndroidSBC structures Houston partnerships around how much integration the local partner keeps in house, with United States projects typically choosing between three levels.

• 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.

For Houston integrators the choice usually comes down to how much of the United States project the local team wants to own versus how much it wants the factory to carry.

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. AndroidSBC ships the dual-screen query terminal with independent display as a standard configuration, and the touch, printer and card reader drivers for it are integrated into the factory image rather than added by the Houston integrator on site.

What is the real difference between the RK3568 tier and the other silicon tiers in the WF-K family?

Answer: The RK3568 tier differs in compute headroom, display capability and NPU availability rather than in board-level interfaces. All WF-K models share the same mounting pattern, the same peripheral pinout and the same firmware baseline, so a United States project can move between tiers without re-designing the enclosure.

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

Answer: Yes. AndroidSBC prepares the conformity file set for United States as part of the order, covering CE, FCC, RoHS and REACH as applicable, plus the destination-specific route. The documents travel with the Houston shipment rather than following it.

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

Answer: For Houston 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, and the custom build is maintained as a branch rather than a one-off, so Houston partners receive updates against their own image for as long as the United States programme runs.

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

Answer: The WF-K family runs a staged OTA channel with rollback. Updates are released against the shared firmware baseline, and Houston integrators can hold a United States estate on a known revision while a new build is validated.

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

Answer: Yes. Boards for Houston can be routed straight into Amazon FBA or a third-party 3PL in United States, with the labelling and packing specification confirmed before the lot is packed.

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

Answer: DOA and RMA cases are managed by lot, with replacement units supplied from a matching build so a Houston partner does not end up with mixed firmware across a United States estate.
