Query LCD Controller Board for Clinic Reception, WF-K3399, AndroidSBC, Stockholm

TL;DR: Query LCD Controller Board for Clinic Reception

AndroidSBC sourcing desk: touch query board pricing held flat through the current quarter serving Stockholm, Sweden. 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 Stockholm and Sweden 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 brand of Wanlin Manufacturing Group, a Shenzhen board maker that runs self-service query terminal Android motherboard production on its own Longgang lines. The WF-K series covers twelve models across eight silicon tiers, from the RK3588 flagship down to the entry A133 part, so a Stockholm buyer can size a query terminal project without changing suppliers halfway through. The plant holds a standing allocation of LPDDR4X and eMMC for the WF-K line, which is how Stockholm projects keep their lead times stable across quarters.

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 Sweden 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 Sweden Buyers

The Stockholm market asks for query terminals that are simple to service, because a failed unit means a closed service station. That shifts the sourcing question towards board consistency and spare-part continuity in Sweden.

Then comes documentation. A Stockholm importer needs the PTS evidence trail behind CE marking with PTS radio interface notification to clear customs in Sweden without holding the shipment at Port of Stockholm for paperwork reasons. That is the backdrop for the Stockholm programme: a 39100-unit requirement placed on September 22, 2026 and routed through the Stockholm - Shanghai lane to keep the schedule honest.

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

The comparison below reflects the configurations AndroidSBC ships to Stockholm against the typical competing query board offered in Sweden.

• 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. Sweden procurement increasingly specifies the dual-screen HD query terminal with mirrored display as part of a wider access programme, which pushes Stockholm 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-K3399 and WF-K8800 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-K8800 and WF-K8801 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-K8801 over boards that re-spin silicon between lots.

That trend favours board-level suppliers in Sweden: the Stockholm buyer who can re-order the same part number two years later is the one who can keep an estate running.

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 Stockholm.
• 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 Stockholm: 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 Stockholm Buyers

The partnership structure offered to Stockholm buyers is deliberately flexible: Sweden 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 Stockholm partner selects, the underlying board, firmware baseline and compliance files are identical, which keeps Sweden 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 Sweden 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 Stockholm buyers.

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

Answer: Yes. Compliance files for Sweden are bundled into the source-factory shipment to Stockholm, 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. Stockholm buyers can start small, then scale once Sweden 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 Stockholm project rather than sold as a generic service, which keeps the Sweden 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 Stockholm estate is live and Sweden 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 Sweden fulfilment centres on behalf of Stockholm 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. Stockholm partners report against the lot number and AndroidSBC matches it to the rig log.
