1920x1080 FHD Query Display Board, WF-K3399

TL;DR: 1920x1080 FHD Query Display Board

AndroidSBC sourcing desk: touch query board pricing held flat through the current quarter serving international market, United States. 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 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.

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 international market 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-K3399 Technical Specifications

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 United States 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 United States Buyers

Sourcing a self-service query terminal board for United States is not only a chip question. A international market 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 international market 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 25700-unit order for international market repeats identically the 7th time it is placed, down to the firmware revision.

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 international market integrator typically finds on competing query boards sold into 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

The category is broadening from single-purpose lookup stations into multi-role information points. United States operators now expect the dual-screen HD query terminal with mirrored display to drive a hall display as well, which is why international market projects increasingly specify dual-screen configurations.

• 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 United States buyers, the market shift means the query terminal decision is now a multi-year supply decision, and international market projects are increasingly evaluated on that basis.

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 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-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 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

The commercial menu for international market integrators has three entries, and United States 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 United States partners start on the distribution track, add the integration track once volumes justify it, and move to private label when international market 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. The dual-screen HD query terminal with mirrored display is a stock configuration on the WF-K self-service query terminal Android motherboard family from AndroidSBC. All tiers are validated against the same firmware build and the same peripheral interface before shipment to international market.

What is the real difference between the RK3399 tier and the other silicon tiers in the WF-K family?

Answer: The RK3399 tier is the right choice when the international market deployment needs exactly its level of video decode and AI capability; above that the extra headroom is paid for but not used, and below it the board cannot sustain the workload.

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

Answer: Yes, and where United States requires a local registration step AndroidSBC supplies the technical file that the international market partner submits, rather than leaving the integrator to reconstruct it.

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

Answer: AndroidSBC sets a pilot-friendly MOQ on the WF-K family. Sample units reach international market in 1-3 days, and a first bulk lot for United States runs 15-30 days from confirmation.

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

Answer: Yes. The WF-K baseline is Android, but United States buyers frequently need a custom Linux image or a stripped Android build, and AndroidSBC delivers both from the Longgang engineering team for international market.

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

Answer: AndroidSBC supports field updates by staged OTA with rollback, plus local update packages where a international market integrator needs to service United States sites without network access.

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

Answer: Yes, and this is a standard route for international market sellers. AndroidSBC prepares FBA-compliant cartons and labels for United States warehouses as part of the shipment rather than as a separate service.

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

Answer: AndroidSBC logs every board to its burn-in result, which is what makes RMA workable for international market integrators running United States estates across many sites.
