Host-attached
USB/SDIO host access with fewer board changes
Wi-Fi Transceiver IoT Connectivity
Add Wi-Fi + BLE connectivity to compact terminals faster
For appliances, sensors, toys, control panels, and lightweight IoT terminals, TXW901 connects through USB/SDIO and separates wireless connectivity, provisioning, and security from the main application board.
BLE provisioning
For onboarding, near-field control, and auxiliary links
Secure link
Supports WPA/WPA2/WPA3 and stable wireless access
IoT terminals need fewer hardware changes, faster access, and easier maintenance
Many IoT products already have a host MCU and application logic. What they lack is production-ready wireless access. Using TXW901 as a host-attached transceiver lets the host keep sensor, button, motor, or display logic while the wireless side focuses on provisioning, networking, security, and compatibility.
Typical Deployment Forms
Each form connects the scenario to hardware priorities such as connectivity, power, imaging, and maintenance.
Sensors and panels
Adds Wi-Fi to sensing, status collection, and panel control.
Connected appliances
Fits host-attached wireless for fryers, purifiers, and cleaning devices.
Toys and compact devices
BLE provisioning plus Wi-Fi remote control for compact terminals.
Solution Path
A lightweight path from host to cloud
The host manages application data over USB/SDIO, BLE handles fast onboarding, Wi-Fi carries networking, OTA, and cloud traffic, and the result is a reusable wireless access module.
Application host
Keeps existing sensor, control, and product logic.
TXW901
Handles Wi-Fi/BLE, driver, and secure connection.
App/cloud
Enables remote control, device management, and OTA.
Hardware integration
Turn wireless into a reusable interface path
For appliances, sensors, and control terminals, board area and schedules are tight. TXW901 can attach through USB2.0 HS or SDIO2.0, turning wireless, antenna, power, and driver work into a clear subsystem that can be reused across products.
- The host does not need to rebuild the wireless stack
- RF and antenna design can be validated separately
- One access design can serve multiple terminals
Product rollout
Small devices still need provisioning, sleep/wake, and router compatibility
IoT issues in the field are rarely about one successful connection. Router changes, weak signals, power recovery, sleep/wake, and many devices online at once matter more. The page organizes evaluation around these production realities.
- BLE provisioning lowers first-use friction
- WPA/WPA2/WPA3 covers mainstream security needs
- USB/SDIO helps reuse drivers and production tests
