Build Faster with the Bluetooth 2.0 Bee Module For Arduino
This DFRobot Bluetooth Bee Bluetooth wireless module adapts the XBEE design. It has a compact size, the pinout is compatible with XBEE which is suitable for all kinds of microcontrollers such as Arduino who have 3.3V power out, also the module supports AT commands for parameter setting. (NOTE: You have to use an XBEE adapter for parameter setting. )
The Bluetooth Bee modules come with an onboard antenna, the antenna provides better signal quality. It acts like a transparent serial port, which works with a variety of Bluetooth adapter and Bluetooth phone.
Important: Use the official DFRobot links below for wiring, sample code, downloads, and the latest setup notes for this SKU.
