HM-10 Transparent Serial Port Bluetooth 4.0 Module with Logic Level Translator

HM-10 Bluetooth module description
Most complete, most convenient, and most stable Bluetooth data transmission, remote control, and data acquisition module
Master-slave in one, transparent transmission, replacing serial port
Remote control, transparent transmission, MCU is unnecessary
Remote data acquisition, transparent transmission, MCU is unnecessary

The HM-10 Bluetooth module for Arduino (Master Slave) uses the TI CC2540 or CC2540 chip, configure 256KB space, and support AT command. Users can change the role (master, slave mode) and the serial port baud rate, equipment name, matching password and other parameters on-demand. It is very flexible to use.
