This is a Bluetooth wireless module based on CSR BC417143 Bluetooth chipset.
It has a compact size and the pinout is compatible with XBEE which is suitable for all kinds of microcontroller systems which have 3.3V power output.
The module can use AT commands to set the baud rate.
The Bluetooth Bee module comes with an onboard antenna which provides a better signal quality. It actslike a transparent serial port. It can work with iPhone and Android devices that support Bluetooth 4.0.
Its baud rate can be modified to use with XBEE adapter.
The module has been tested with several Bluetooth adapters on the market and matched to use with the Bluetooth of laptops and mobile phones.
