Bluetooth Bee

The Bluetooth Bee is a compact Bluetooth wireless module based on the CSR BC417143 Bluetooth chipset. It features a small form factor with an XBEE-compatible pinout, making it suitable for a wide range of microcontroller systems that provide 3.3V power output.

The module supports AT commands for configuration, allowing users to set parameters such as the baud rate easily. It comes with an onboard antenna, which ensures stable performance and improved signal quality.

The Bluetooth Bee operates as a transparent serial port, enabling seamless wireless serial communication. It is compatible with a wide range of Bluetooth adapters and Bluetooth-enabled devices, including laptops and mobile phones. The module has been tested with commonly available Bluetooth adapters to ensure reliable operation.

The baud rate can be modified using an XBEE adapter, and when used with an XBEE-compatible Arduino controller base, it enables convenient Bluetooth wireless control for embedded projects.
