HM-10 4.0 Bluetooth Module

The HM-10 is a Bluetooth 4.0 Low Power module and is capable to communicate with BLE capable devices (e.g. iPhone and iPad). It is fully configurable by a rich and well documented AT command-set and allows transparent data communication via serial UART (default baudrate 9600bps). The HM-10 is a small 3.3v SMD Bluetooth 4.0 BLE module based on the TI CC2540 or CC2541 Bluetooth SOC (System On Chip). The HM-10 is has become a very popular Bluetooth 4 BLE module for use with the Arduino. This HM-10 comes on a breakout board for easier integration with your projects.
