Dual-screen Mirrored Display Query Terminal Board, WF-K3288, AndroidSBC, Los Angeles

TL;DR: Dual-screen Mirrored Display Query Terminal Board

AndroidSBC sourcing desk: touch query board pricing held flat through the current quarter serving Los Angeles, United States. The WF-K3288 self-service query terminal Android motherboard spans the legacy query terminal refresh with hall display and eleven sister models in the WF-K series, all built on the RK3288 quad-core ARM Cortex-A17 1.8GHz SoC with the ARM Mali-T764 GPU, 1080p HDMI plus LVDS, and Android 10 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-K family from the Longgang source factory in Shenzhen to Los Angeles 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 Los Angeles 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-K3288 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3288 (legacy query terminal refresh with hall 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-K3288-A variant is the typical configuration for the installed-base query terminal refresh use case, with a sustained weekly capacity of 5000 pcs/wk.

Challenges in Sourcing Self-Service Query Terminal Android Motherboards for United States Buyers

Buyers in Los Angeles often treat a self-service query terminal as a commodity board, then discover that the printer driver, the card reader stack and the kiosk-mode lockdown each need separate validation against United States deployment conditions.

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 Los Angeles integrators pay for in schedule, not just money. The factory answers with lot-level BOM control, so the Los Angeles order of 23900 units is the 3rd in a series that never re-qualifies the peripheral stack.

Competitive Comparison: WF-K3288 vs Competing Self-Service Query Terminal Android Boards

The table below puts the WF-K self-service query terminal board against what a Los Angeles 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

Growth in the query terminal segment is being driven by labour economics as much as by technology. In United States the legacy query terminal refresh with hall display lets operators cover longer hours with the same headcount, and Los Angeles 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-K3288 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.

For Los Angeles integrators the implication is straightforward. Competing on the query terminal itself is difficult; competing on the integration package that reaches United States is where margin survives.

Partner Success Story: Nordweg Innbyggertorg (municipal citizen service operator)

The Nordweg Innbyggertorg rollout in the Nordic public service segment shows how the WF-K family from AndroidSBC supports Los Angeles integrators. Nordweg Innbyggertorg deployed 23900 compact query terminals across municipal service points.

• OEM relationship: AndroidSBC private-label SKU shipped with Nordweg Innbyggertorg 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 FCC / UL conformity, all bundled into the Shenzhen source-factory shipment.

According to Nordweg Innbyggertorg Programme Director for Nordic Public Service: Nordweg Innbyggertorg replaced counter-side lookup binders with the WF-K compact board, and 23900 units went into Los Angeles service points without any change to the existing counter furniture.

Field Report: installed-base query terminal refresh at a social security service hall

YANTIAN, Shenzhen, September 22, 2026 - Jin Tao, AndroidSBC field desk. Because United States sites range from air-conditioned lobbies to unheated entrances, the WF-K3288 batch was cleared at both ends of the rated window. The WF-K3288 self-service query terminal Android motherboard order for Los Angeles, United States cleared the burn-in station on schedule and is en route via the Los Angeles - Shanghai lane.

The WF-K3288 legacy query terminal refresh with hall display production lot includes the WF-K3288-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 Jin Tao, AndroidSBC field desk, YANTIAN, 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-K3288 Application Scenarios

The WF-K3288 legacy query terminal refresh with hall 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-K3288-A configuration is the typical build for the installed-base query terminal refresh use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.

• Hospital and clinic information points: the WF-K3288 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in Los Angeles.
• 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-K3600 runs tax, social security and real estate information lookup, with printing available on the same board.
• Shopping mall directories: the WF-K3601 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-K3602 has to stay readable under strong ambient light.
• Retail and pharmacy price or product lookup: compact stations where the WF-K3566 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 Los Angeles: 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 Los Angeles Buyers

Three tracks are open to Los Angeles integrators, and the difference between them is where the United States partner wants to add its own value.

• 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 Los Angeles brand recognition matters more than margin per unit.

Frequently Asked Questions

Does the WF-K self-service query terminal Android motherboard family support a legacy query terminal refresh with hall display?

Answer: Yes. AndroidSBC treats the legacy query terminal refresh with hall 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 RK3288 tier and the other silicon tiers in the WF-K family?

Answer: The RK3288 tier carries its own process node, GPU and NPU rating, and AndroidSBC publishes all three per model so Los Angeles integrators can compare on facts rather than on marketing labels.

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

Answer: Yes. AndroidSBC handles the compliance route for United States directly, and Los Angeles 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 Los Angeles integrator can pilot one tier for United States 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 Los Angeles requirement and validated on the same production rig that ships United States 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 Los Angeles integrators decide when a United States 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, and where a Los Angeles seller runs its own 3PL arrangement in United States, AndroidSBC ships to that warehouse on the same terms as a direct buyer order.

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 Los Angeles integrators this keeps United States deployments serviceable without holding large local stock.
