VCC: positive pole of the power source.BRK: break connect, it means breaking the Bluetooth connection, generally keep it unconnected.STATE: state test pins, connected to an internal LED, generally keep it unconnected.The Bluetooth 4.0 HM-10 is basically a breakout board for cc2541, it broke out the LED pins, RX/TX and also adding the voltage regulator that regular 5v to 3.3 v.Ĭlones available in market have on board only single crystal and the Firmware of clones support limited AT commands.Clones are mostly named as MLT-BT05 It is fully configurable by a rich and well documented AT command-set and allows transparent data communication via serial UART (default baud rate 9600 bps).
You can use it simply for a serial port replacement to establish connection between MCU & your embedded project The module is designed by using the Texas Instruments CC2541 Bluetooth low energy(BLE) System on Chip (SoC). This module is used for establishing wireless data communication. The HM-10 BLE Wireless Module-Original is a readily available Bluetooth 4.0 module, which can configure as either Master or slave.
