This is a dual-mode Bluetooth 5.1 expansion module designed for the Raspberry Pi Pico. It is controlled via UART AT commands, with Serial Port Profile (SPP) and Bluetooth Low Energy (BLE) support. Designed to allow the communication between your Pico and a mobile phone*, this module comes pre-soldered and ready to fit to your Pico (with male headers soldered). UART pin selection is available via solder bridge if required. * Currently only communication with mobile phones is officially supported. Compatibility with other Bluetooth devices has not been tested - your mileage may vary! Note: Raspberry Pi Pico not included. You'll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.
