HC-42 Bluetooth 5.0BLE Serial Port Module without Baseplate Overview
The HC-42 Bluetooth 5.0BLE Serial Port Module without Baseplate is a compact nRF52832-based wireless transceiver designed for embedding Bluetooth Low Energy connectivity into custom electronics. It provides a UART-style serial interface and breakout pins for GPIO, allowing it to function both as a Bluetooth data link and as a standalone MCU controller.
Key Features of HC-42 Bluetooth 5.0BLE Serial Port Module without Baseplate
- nRF52832 SoC with BLE 5.0 support for up to 2 Mbps data rate and –96 dBm sensitivity
- Wide operating voltage range (1.8 V–3.6 V) and ultra-low no-load current (0.3 µA)
- On-board PCB antenna with typical reference range of 40 m at 2 Mbps
- Breakout of MCU GPIOs via half-hole design for easy prototyping and mass production
- Configurable via AT commands over serial interface for custom firmware-free setup
- Genuine product and fast shipping from Zbotic ensures you get the module quickly and reliably
Applications and Use Cases
- Wireless serial data link between microcontroller boards and smartphones or PCs
- Bluetooth Low Energy sensor hubs for environmental or wearable devices
- Remote control modules for robots, drones or home automation appliances
- BLE beacons and location tracking systems
- Standalone MCU projects leveraging nRF52832 GPIO breakouts
- Prototyping Bluetooth peripherals without soldering large baseplates
How to Use HC-42 Bluetooth 5.0BLE Serial Port Module without Baseplate
To use the HC-42, power it with 1.8–3.6 V on VCC and GND, then connect the module’s TX/RX pins to your host MCU’s RX/TX through appropriate level shifting if needed. Issue AT commands via a serial terminal at the default baud rate to configure BLE name, speed, and pairing mode. Once configured, pair the module with a BLE central device and exchange data over the transparent serial link or control attached peripherals via the breakout GPIOs.

Frequently Asked Questions
Can I use the HC-42 module without an external MCU?
Yes. The HC-42 breaks out multiple GPIOs from the nRF52832 chipset, allowing you to program and control external LEDs, sensors or actuators directly via AT commands or custom firmware.
What is the maximum operating range of this module?
The HC-42’s on-board PCB antenna achieves a practical line-of-sight range of up to 40 meters at 2 Mbps BLE 5.0 data rate, subject to environmental conditions and RF interference.
How do I update the module’s settings?
Connect to the module’s UART interface at the default baud rate, enter AT command mode, and send configuration commands such as AT+NAME, AT+BAUD, or AT+POWER. Settings are saved in onboard flash memory.
