HM 10 Bluetooth Module

HM 10 Bluetooth Module

The HM-10 module provides a simple UART interface, allowing seamless wireless communication between devices.
It is fully compatible with Arduino, Raspberry Pi, ESP32, and other 3.3V/5V logic systems through its TTL serial interface.
Using AT commands, users can easily configure parameters such as the module name, baud rate, transmission power, and operation mode (Master/Slave).

This module can communicate directly with BLE-enabled smartphones or tablets without needing a custom driver, which makes it perfect for Bluetooth app-controlled projects.
