TL8800D4UA1-Z WiFi Module — Dual-Band 1T1R USB Module (AIC8800D40)

TL8800D4UA1-Z

The TL8800D4UA1-Z is a compact dual-band WiFi module built on the AIC8800D40 chip platform. Combining 2.4GHz and 5.8GHz operation with a 1T1R antenna configuration and a USB interface, it gives product engineers a straightforward way to add dual-band WiFi connectivity to space-constrained designs. At just 12.2 × 12.9 mm, the module is suited to embedded layouts where board area is at a premium.

The module is manufactured by Shenzhen TrolinkTek Technology Co., Ltd., a short-range wireless module specialist founded in 2005. With 20 years of focus on WiFi, Bluetooth, and Zigbee modules, TrolinkTek handles R&D, production, and sales in-house — a structure that supports both standard module supply and customized OEM/ODM programs.

This page covers the verified specifications, typical applications, integration considerations, and ordering paths for the TL8800D4UA1-Z. For design-specific questions, our engineering team can be reached through the contact links at the bottom of the page.

Key Specifications

  • Model: TL8800D4UA1-Z
  • Chip platform: AIC8800D40
  • Antenna configuration: 1T1R (single transmit, single receive)
  • Interface: USB
  • Frequency bands: Dual-band 2.4GHz + 5.8GHz
  • Form factor: Compact footprint, 12.2 × 12.9 mm
  • Manufacturer: Shenzhen TrolinkTek Technology Co., Ltd.

Model naming convention: The model number follows TrolinkTek's internal naming rule. "TL" identifies the TroLink brand, followed by the module class and chip designation. This makes it possible to trace a part number back to its module family and underlying silicon platform at a glance.

Applications

The TL8800D4UA1-Z belongs to a module class used across a range of connected devices. Typical applications include:

  • IPC cameras — dual-band WiFi supports video streaming in both crowded 2.4GHz environments and cleaner 5.8GHz spectrum.
  • OTT boxes — streaming media devices benefit from 5.8GHz throughput and reduced interference.
  • Smart home devices — connected appliances, sensors, and control hubs.
  • POS terminals — payment and retail terminals requiring reliable wireless links.
  • Projectors — wireless display and content delivery.
  • Tablets — mobile computing devices needing compact dual-band connectivity.

The common thread across these applications is a need for dual-band WiFi in a small footprint, with a USB host interface already available on the main processor or SoC.

Integration Notes

SMT-friendly design. The module is designed for standard surface-mount assembly. TrolinkTek operates standardized SMT lines, and the module footprint is compatible with conventional reflow processes. For engineers finalizing a PCB layout, this means the module can be placed and soldered alongside other SMT components without special handling requirements.

USB interface. Integration centers on the USB interface, which connects the module to the host processor. Designers should follow good high-speed USB layout practice — controlled impedance traces, length matching where required, and keeping the USB pair away from noisy switching sources.

Antenna consideration. With a 1T1R configuration, the design uses a single antenna path covering both 2.4GHz and 5.8GHz. Antenna selection and placement should account for both bands, and keep-out areas around the antenna should be respected in the mechanical and PCB design. The 12.2 × 12.9 mm module footprint leaves room for careful antenna routing even in compact enclosures.

Driver availability. Driver packages are provided with the datasheet; confirm your host OS/kernel with our engineers during the evaluation stage.

Evaluation support. TrolinkTek offers free samples so engineering teams can validate RF performance, driver integration, and layout assumptions on their own hardware before committing to production. This is particularly useful for teams designing the module into a new PCB for the first time.

OEM/ODM and Manufacturing Support

TrolinkTek is structured as a full-stack module supplier: in-house R&D, production, and sales under one roof. For customers who need more than a standard catalog module, this enables OEM/ODM engagement — customized module configurations, branding, and packaging tailored to a specific product program.

Quality and compliance are managed through the company's ISO9001 quality system. The company holds FCC, CE, SRRC, and RoHS certifications. These cover the core requirements for wireless products sold into major markets, including North America, Europe, and China.

Manufacturing runs on standardized SMT lines, which supports consistent output quality and gives customers a predictable production path from prototype through volume.

For teams evaluating the TL8800D4UA1-Z, the practical next steps are typically: request free samples, confirm driver compatibility for the host platform, and review the module footprint against the target PCB. Our team supports each of these stages.

FAQ

Q: Can I get samples before placing a production order?
