HC-05 and HC-06 Bluetooth Serial Modules for Arduino

Add a wireless serial link to a compatible Arduino or microcontroller project with an HC-05 or HC-06 Bluetooth module. The module connects through VCC, GND, TXD and RXD pins, keeping the wiring straightforward for supported UART applications.

Choose the Bluetooth module for your project

• ✅ ✅ Send serial data without a wired link: Bluetooth communication can connect a compatible controller to another Bluetooth device.
• ✅ ✅ Match the model to your setup: Choose HC-05 or HC-06 according to the role and configuration your project requires.
• ✅ ✅ Connect to common microcontroller pins: The source lists a 3.3–5V supply and UART-style VCC, GND, TXD and RXD connections.

Use it for a suitable Arduino or computer-connected serial project after checking voltage levels and the module’s pinout. The listing warns that incorrect wiring can damage the module; verify connections before applying power.

Each variant is the selected module; cables, controller board and other project parts are not confirmed as included. The source does not specify a communication range.

Details: HC-05 or HC-06; Bluetooth serial module; stated supply range 3.3–5V; VCC/GND/TXD/RXD interface.

Select the module that matches your project’s communication requirements.
