HM-10 Bluetooth 4.0 BLE Module | Pro Tronix

Product Description

A high-efficiency Bluetooth 4.0 Low Energy (BLE) serial transceiver module designed for smart wireless communication, remote data logging, and IoT automation in Arduino and ESP32 projects. Powered by the reliable Texas Instruments CC2541 system-on-chip, this HM-10 breakout board brings low-power proximity tracking and high-speed data streaming to iOS, iPhone, and Android platforms. It operates as a full hardware-level pass-through UART pipeline, converting standard serial data seamlessly into wireless packets with zero configuration required. Featuring full iBeacon advertising support, a built-in logic level shifter, and a comprehensive AT command set, this module provides an exceptional foundation for building custom smart keys, remote control mobile applications, and long-range environmental sensor beacons.

Pinout / Layout Connections

The breakout board routes its logic paths and power lines via a standard 6-pin male header interface:

• STATE Pin: Device state indicator output. Changes logic states to signal whether the module is currently connected or searching for a master device.

• VCC Pin: Power supply input, accepts DC +3.6V to +6V (equipped with an onboard low-dropout voltage regulator).

• TXD Pin: Asynchronous Serial Data Output. Transmits received wireless data to the host microcontroller’s RX line.

• RXD Pin: Asynchronous Serial Data Input. Receives data from the host microcontroller’s TX line (fully 5V logic safe).

• GND Pin: Common system ground (0V) reference.

• BRK (Break) Pin: Hardware interrupt pin. Pull HIGH or LOW to forcefully disconnect active Bluetooth connections or reset link states.

Applications

• Cross-Platform Mobile Apps: Perfect for establishing secure, dual-compatibility wireless links between custom hardware and custom-built iOS or Android apps.

• Micro-Location iBeacon systems: Excellent for setting up proximity marketing beacons, indoor navigation maps, and automated automated check-in counters.

• Ultra-Low Power Wireless Nodes: Ideal for field telemetry equipment requiring periodic data transmissions over long periods using low power.

Compatibility

The HM-10 CC2541 module communicates via universal asynchronous serial streams, ensuring plug-and-play compatibility across platforms:

• All Apple iOS Devices (iPhone, iPad) natively supporting Bluetooth 4.0 BLE architectures without needing specialized MFi licensing.

• Android Smartphones and Tablets running modern Android versions with active BLE hardware configurations.

• Arduino Board Series (Uno, Nano, Mega, Pro Micro) utilizing simple hardware or software serial interfaces.

• ESP32 and ESP8266 development boards (Fully compatible with native 3.3V UART signal channels).
