HC-42 6pin Bluetooth 5.0BLE Serial Port Module
Description
The HC-42 6pin Bluetooth 5.0BLE Serial Port Module is a digital transmission module that operates on the Bluetooth BLE V5.0 protocol. It works on the 2.4GHz ISM frequency band and uses GFSK modulation. The module can transmit up to 4dBm and receive signals as low as -96dBm.
The module supports BLE (Bluetooth Low Energy) protocol, which is different from Bluetooth in terms of power consumption and data transfer. Bluetooth uses more power and can handle large amounts of data, while BLE is suitable for transferring small amounts of data quickly between nearby devices. BLE devices can run for years on a small battery, making them ideal for IoT applications.
Note: The product dimensions may have ±2% error. Color also may vary due to light effect.

How to Use HC-42 6pin Bluetooth 5.0BLE Serial Port Module
Begin by wiring the six pins: connect VCC (1.8–3.6 V) and GND to your power source, then link TXD and RXD to your microcontroller’s RX and TX pins (use matching voltage levels). Power on the module, pair it with a BLE host, and send or receive data transparently over UART at the selected air rate. For configuration, issue AT commands over the serial link or adjust parameters via your BLE master device.

Frequently Asked Questions
Can the HC-42 module work with 3.3V microcontrollers?
Yes. The HC-42 operates between 1.8 V and 3.6 V, making it directly compatible with 3.3 V logic levels used by most modern microcontrollers like Arduino Pro, ESP32 and STM32 boards.
What is the maximum reliable communication distance?
Under open-field conditions at 2 Mbps, you can expect up to 40 m of range. Indoors or with obstacles, actual reliable distance may vary but typically remains suitable for room-to-room links.
Does the HC-42 support transparent UART communication?
Yes. Once paired, the HC-42 operates as a transparent serial bridge: any bytes sent to its TXD pin are transmitted over BLE and delivered to the remote RXD pin, with no additional framing required.
