HM-10 Bluetooth Module-China Make

The HM-10 module is a small Bluetooth 4.0 module that utilizes the Texas Instruments CC2540 or CC2541 BLE System SoC (System on Chip). It operates on 3.3v SMD and can be controlled through the serial UART connection by sending AT commands. The main purpose of the HM-10 module is for wireless data communication, but it is crucial to note that it can only connect with Bluetooth 4.0 based modules, and not with Bluetooth 2/2.1 modules like HC-05 and HC-06.

Due to its standard UART serial connection, the HM-10 bluetooth module is widely used with the Arduino and is available in two versions: HM-10C and HM-10S. The HM-10S is primarily for data transmission, whereas the HM-10C serves as a remote control version with PIO status. The HM Bluetooth modules use CSR or TI CC254x or Cypress chips, allowing them to operate as both master and slave roles..
