AirPrime BX3105

Sierra Wireless | Bluetooth and Wi-Fi Module

The BX3105 development kit is a small form factor evaluation board, powered by USB. It exposes all the BX3105 pin interfaces via headers. The BX3105 development kit has a UART to USB converter running at 1Mb/s for direct connection of the UART to a PC. The BX3105 device supports Bluetooth Classic, BLE and Wi-Fi operation.  The board has a TLV320AIC3111 audio CODEC connected to the BX3105 via the I2S / I2C interface. The development kit also has a LSM6DS3TR 3D digital accelerometer and 3D digital gyroscope for motion sensing using the BX3105 integrated I2C support. Designers can make use of the integrated IP stack and MQTT software to speed IoT development.
