Description
🔵 HM-10 BLE Bluetooth 4.0 Module
CC2540 / CC2541 | Arduino | Android | iOS | Serial Wireless Module
📌 Overview
The HM-10 BLE Bluetooth 4.0 Module is a low-power wireless communication module based on the TI CC2540 or CC2541 chipset. It supports Bluetooth Low Energy (BLE 4.0) and allows wireless serial communication between:
-
Arduino
-
ESP8266 / ESP32
-
STM32
-
Raspberry Pi
-
Android smartphones
-
iOS devices
Unlike HC-05/HC-06, the HM-10 supports iOS devices because it uses BLE technology.
📡 Core Features
✔ Bluetooth 4.0 (BLE)
✔ Low Energy consumption
✔ Supports iOS & Android
✔ UART Serial Communication
✔ AT Command configuration
✔ Compact size
✔ Fast connection
