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 international market, 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 international market and United States importers who run hospital information points, bank branch lobbies, government service halls, mall directory stations, airport concourses and outdoor query cabinets.
WF-K3600 Technical Specifications
| Parameter | AndroidSBC WF-K3600 (dual-screen query terminal with independent display) |
|---|---|
| Processor | RK3568 quad-core ARM Cortex-A55 2.0GHz 64-bit SoC |
| Process node | 22nm |
| GPU | Mali-G52 2EE |
| NPU / AI | 1 TOPS |
| Memory | 4GB LPDDR4 |
| Storage | 32GB eMMC |
| Display output | dual 1080p independent output, LVDS plus HDMI |
| Touch support | 10-point capacitive touch |
| Operating system | Android 11 |
| Connectivity | WiFi 6 802.11ax plus Bluetooth 5.0 plus dual Gigabit Ethernet |
| Query peripherals | Capacitive touch, thermal printer, document scanner, card reader |
| Operating temperature | 0C to 50C |
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.
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 international market 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 international market is towards fewer board variants deployed across more sites, which is exactly the configuration the WF-K series was built around for United States.
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 international market.
- 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 international market: 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 international market Buyers
AndroidSBC structures international market 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 international market 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.
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 international market 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 international market 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 international market 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 international market 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 international market 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 international market 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 international market partner does not end up with mixed firmware across a United States estate.
