HC-06 Bluetooth 2.0 Slave Module (4-Pin, CSR BC04)
The HC-06 is a classic Bluetooth 2.0+EDR serial slave module based on the CSR BC04 chip, providing a simple wireless UART bridge for Arduino and microcontroller projects. It operates from 3.3V to 6V and features a built-in PCB antenna for a typical range of 10 meters.
Features
- Slave-Only Bluetooth 2.0+EDR Module: Designed to be paired with a master device like a PC or smartphone, enabling simple wireless serial data exchange.
- CSR BC04 Chipset with PCB Antenna: Reliable 2.4GHz RF core with an integrated antenna for a compact, solder-and-go solution.
- Wide 3.3V to 6V Power Input: Features an onboard 3.3V regulator, allowing direct connection to 5V Arduino systems without a logic level shifter.
- Simple 4-Pin UART Interface: Breakout for VCC, GND, TXD, and RXD pins for straightforward integration with microcontrollers.
- Configurable via AT Commands: Set module name, pairing PIN, and baud rate (default 9600) when not connected to a Bluetooth master.

The HC-06 Bluetooth module is a foundational component for adding wireless serial communication to embedded systems and DIY electronics. It implements the Bluetooth 2.0 specification with Enhanced Data Rate (EDR) on the proven CSR BC04 transceiver, operating as a dedicated slave device. This means it cannot initiate connections but awaits pairing from a master, making it ideal for creating wireless sensors, data loggers, or remote control interfaces that communicate with a central host.
Power management is handled by an integrated 3.3V low-dropout regulator, accepting a wide input range from 3.6V to 6V DC, which simplifies power supply design. The module’s current consumption is modest, drawing approximately 30-40mA during the pairing process and dropping to around 8-10mA during active data communication. Its compact form factor (27mm x 13mm) houses a printed circuit board (PCB) antenna, providing a Class 2 power level with an effective open-space range of up to 10 meters.
