HM-10 Bluetooth module is a Bluetooth Low Energy (Bluetooth 4.0) development module based on the CC02541 Chip from Texas Instruments. The module communicates through UART protocol using AT commands. It can be used to communicate with all BLE devices like Fitness bands, Bluetooth trackers etc or even used as an iBeacon.
The module has a built-in CPU that supports IO expansion, 14-bit two channel ADC, 120Hz four channel PWM etc. It has a range of 60 meters and consumes very low power in standby mode. The module can act both as a Master and as a Slave.
