TL;DR: RK3568 HDMI 2.0 Query Board
AndroidSBC release: twelve-model WF-K self-service query terminal motherboard family opens for volume orders serving Winnipeg, Canada. The WF-K3399 self-service query terminal Android motherboard spans the dual-screen HD query terminal with mirrored display and eleven sister models in the WF-K series, all built on the RK3399 dual Cortex-A72 1.8GHz plus quad Cortex-A53 SoC with the ARM Mali-T860 MP4 GPU, dual 1080p output, HDMI plus eDP, 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 Winnipeg and Canada 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 is the export arm of Wanlin Manufacturing Group. Its WF-K series addresses the self-service query terminal segment with twelve boards on eight chips, all produced in the Longgang source factory in Shenzhen. Winnipeg and Canada buyers typically start from one pilot model and then scale the same board across a wider estate. The factory ships to Canada on a factory-direct basis, with the driver SDK, compliance files and mounting drawings bundled into the same carton as the boards.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3399 (dual-screen HD query terminal with mirrored 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 Canada importers sourcing the WF-K family, the WF-K3399-A variant is the typical configuration for the dual-screen HD mall directory rollout use case, with a sustained weekly capacity of 5000 pcs/wk.
Challenges in Sourcing Self-Service Query Terminal Android Motherboards for Canada Buyers
The hard part of a query terminal project in Canada is rarely the processor. It is keeping the touch controller, the printer firmware and the peripheral interfaces on one qualified baseline while Winnipeg rolls the same board across very different sites.
Public-sector tenders in Winnipeg now ask for the compliance chain up front. The ISED certification with a CSA or UL safety listing route used in Canada has to be traceable from the board label back to the test house, which is a sourcing criterion rather than a formality. AndroidSBC deals with it by treating the Winnipeg requirement as one lot of 4900 units on one BOM, quoted on September 22, 2026 and shipped over the Vancouver - Shanghai lane.
Competitive Comparison: WF-K3399 vs Competing Self-Service Query Terminal Android Boards
The table below puts the WF-K self-service query terminal board against what a Winnipeg integrator typically finds on competing query boards sold into Canada.
- 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
Growth in the query terminal segment is being driven by labour economics as much as by technology. In Canada the dual-screen HD query terminal with mirrored display lets operators cover longer hours with the same headcount, and Winnipeg projects are typically justified on exactly that basis.
- Volume shift to board-level sourcing: more integrators now buy the motherboard rather than the finished kiosk, which is why the WF-K3399 and WF-K8801 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-K8801 and WF-K3600 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-K3600 over boards that re-spin silicon between lots.
For Winnipeg integrators the implication is straightforward. Competing on the query terminal itself is difficult; competing on the integration package that reaches Canada is where margin survives.
Partner Success Story: Northline Information Flow Group (multi-site service network operator)
The Northline Information Flow Group rollout in the North America service networks segment shows how the WF-K family from AndroidSBC supports Winnipeg integrators. Northline Information Flow Group retrofitted 4900 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 ISED Canada conformity, all bundled into the Shenzhen source-factory shipment.
According to Northline Information Flow Group VP Service Operations for North America Service Networks: 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 4900 units were upgraded in Winnipeg without touching the enclosures.
Field Report: dual-screen HD directory query rollout at a shopping mall
BAOLONG, Shenzhen, September 22, 2026 - Ke Xin, AndroidSBC field desk. The WF-K3399 run shipped with the dual-screen HD query terminal with mirrored display profile pre-flashed, which shortens the commissioning step for Canada integrators. The WF-K3399 self-service query terminal Android motherboard order for Winnipeg, Canada cleared the burn-in station on schedule and is en route via the Vancouver - Shanghai lane.
The WF-K3399 dual-screen HD query terminal with mirrored display production lot includes the WF-K3399-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 Canada integrators, the ISED Canada conformity plus ISED certification with a CSA or UL safety listing paperwork is bundled.
Filed by Ke Xin, AndroidSBC field desk, BAOLONG, Shenzhen. Canadian clinics and provincial service centres favour one touch query terminal at each entrance plus a wall-mounted information display inside the hall.
WF-K3399 Application Scenarios
The WF-K3399 dual-screen HD query terminal with mirrored 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-K3399-A configuration is the typical build for the dual-screen HD mall directory rollout use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.
- Hospital and clinic information points: the WF-K3399 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in Winnipeg.
- 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-K3601 runs tax, social security and real estate information lookup, with printing available on the same board.
- Shopping mall directories: the WF-K3602 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-K3566 has to stay readable under strong ambient light.
- Retail and pharmacy price or product lookup: compact stations where the WF-K3288 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 Winnipeg: 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 Winnipeg Buyers
The commercial menu for Winnipeg integrators has three entries, and Canada partners usually start on one before adding the others as volumes grow.
- 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.
In practice Canada partners start on the distribution track, add the integration track once volumes justify it, and move to private label when Winnipeg brand recognition matters more than margin per unit.
Frequently Asked Questions
Does the WF-K self-service query terminal Android motherboard family support a dual-screen HD query terminal with mirrored display?
Answer: Yes. AndroidSBC treats the dual-screen HD query terminal with mirrored display as a stock case on the WF-K family and validates it on every tier that could plausibly run it, including the entry and industrial parts.
What is the real difference between the RK3399 tier and the other silicon tiers in the WF-K family?
Answer: The RK3399 tier carries its own process node, GPU and NPU rating, and AndroidSBC publishes all three per model so Winnipeg integrators can compare on facts rather than on marketing labels.
Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for Canada?
Answer: Yes. AndroidSBC handles the compliance route for Canada directly, and Winnipeg buyers receive the certificate set with the shipping documents so customs clearance is not held on paperwork.
What are the MOQ and lead time for a first order of the WF-K self-service query terminal family?
Answer: MOQ is quoted per model rather than per family, so a Winnipeg integrator can pilot one tier for Canada without buying across all twelve. Samples take 1-3 days and bulk lots 15-30 days.
Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?
Answer: Yes. AndroidSBC develops custom Android ROM and custom Linux builds for the WF-K family, with the work scoped against the Winnipeg requirement and validated on the same production rig that ships Canada orders.
How are software updates and long-term support handled on the WF-K family?
Answer: Updates are delivered through a staged OTA channel with rollback support, and Winnipeg integrators decide when a Canada estate moves to a new build rather than being pushed onto it.
Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?
Answer: Yes. AndroidSBC ships to Amazon FBA and 3PL consolidation warehouses, including labelling, carton marking and pallet configuration matched to the Canada destination that Winnipeg buyers specify.
How are RMA and DOA replacements handled on the WF-K self-service query terminal family?
Answer: DOA units are replaced from the next available lot, and RMA cases are tracked by lot number. For Winnipeg integrators this keeps Canada deployments serviceable without holding large local stock.
