Description
The HM-10 BLE Module enables low-power wireless communication between microcontrollers, smartphones, tablets, and other BLE-enabled devices.
It supports UART (TX/RX) serial communication and can operate in central or peripheral mode, making it versatile for a wide range of IoT applications.
The module is commonly used with Arduino, ESP32, ESP8266, and Raspberry Pi, providing reliable BLE communication for smart devices, sensors, wearables, and home automation systems.
With a compact form factor and low energy consumption, HM-10 is ideal for battery-powered projects and applications where classic Bluetooth is too power-intensive.
