64GB eMMC Query Kiosk Board, WF-K3399, AndroidSBC, San Jose

TL;DR: 64GB eMMC Query Kiosk Board

AndroidSBC peripheral desk: printer, scanner and card reader driver SDK declared production-ready serving San Jose, 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 San Jose 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 has supplied board-level hardware to overseas integrators for years, and the WF-K self-service query terminal line is its dedicated query answer. Twelve models, eight platforms, one Longgang production base in Shenzhen, and a single peripheral driver SDK that San Jose teams flash once and reuse across projects. 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

Self-service query terminals in San Jose live in public space, which means the board must tolerate dust, unskilled handling and long unattended hours, not just meet a datasheet in a United States laboratory.

Add the compliance layer and the picture gets tighter. For United States the paperwork runs through FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing, and a board that was never validated against it turns into a re-test cycle that San Jose integrators pay for in schedule, not just money. The factory answers with lot-level BOM control, so the San Jose order of 48200 units is the 2nd in a series that never re-qualifies the peripheral stack.

Competitive Comparison: WF-K3399 vs Competing Self-Service Query Terminal Android Boards

The comparison below reflects the configurations AndroidSBC ships to San Jose against the typical competing query board offered in 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

Information access is being treated as infrastructure in United States, and that changes what is procured. Instead of one-off kiosks, San Jose operators specify the dual-screen HD query terminal with mirrored display as a standard unit to be repeated across a whole estate on the same firmware.

• 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-K1331 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-K1331 and WF-K6180 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-K6180 over boards that re-spin silicon between lots.

What this means for San Jose is that the query board is no longer a disposable line item. It is the component that determines whether United States deployments can be extended rather than rebuilt.

Field Report: dual-screen HD directory query rollout at a shopping mall

SHENZHEN, September 22, 2026 - Bin Yu, AndroidSBC field desk. The WF-K3399 batch was logged against the firmware revision before packing, so United States sites can be matched to a known build. The WF-K3399 self-service query terminal Android motherboard order for San Jose, United States cleared the burn-in station on schedule and is en route via the Los Angeles - 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 United States integrators, the FCC Part 15 and FCC ID for radio modules, plus UL or ETL safety listing paperwork is bundled.

Filed by Bin Yu, AndroidSBC field desk, 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-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 San Jose.
• 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-K5270 runs tax, social security and real estate information lookup, with printing available on the same board.
• Shopping mall directories: the WF-K8800 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-K8801 has to stay readable under strong ambient light.
• Retail and pharmacy price or product lookup: compact stations where the WF-K3600 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 Jose: 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 Jose Buyers

The partnership structure offered to San Jose buyers is deliberately flexible: United States integrators can take the board alone, take it with the driver stack, or take it as a private-label programme.

• 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.

Whatever track a San Jose partner selects, the underlying board, firmware baseline and compliance files are identical, which keeps United States conversations about commercial terms rather than technical risk.

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, and it is qualified on the same production line as the rest of the family. The dual-screen HD query terminal with mirrored 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 RK3399 tier and the other silicon tiers in the WF-K family?

Answer: The RK3399 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 Jose 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 Jose, 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 Jose 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 Jose 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 Jose 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 Jose 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 Jose partners report against the lot number and AndroidSBC matches it to the rig log.
