FireBeetle Board-328P with BLE4.1

The DFRobot FireBeetle series are power-saving microcontrollers specially designed for Internet of Things (IoT) projects. These series microcontrollers target low-power IoT nodes to quickly and easily build the IoT hardware platform. 

This Bluetooth controller combines Bluetooth Low Energy 4.1 with the Arduino controller and offers similar features to the previous Bluno series, but with lower power consumption. FireBeetle BLE 4.1 is compatible with the Bluno series (BLE 4.0) but is much more powerful. The board is equipped with a more stable DIALOG Bluetooth 4.1 chip which supports a maximum transmission rate of 4Kbyte/s and low power consumption (25uA POWER DOWN), making it perfect for low power consumption applications.  

Features of the FireBeetle Board-328P:

• Compatible with products of the DFRobot FireBeetle series
