China Quality HC-05 6pin Bluetooth Module (Slave) No Button B GRADE
Product Description:
The HC-06 is a popular Bluetooth module designed to provide easy wireless serial connectivity for your devices. Operating exclusively in slave mode, this module simplifies data exchange with other Bluetooth-enabled devices, such as smartphones, computers, and more. It works just like a standard UART connection once paired, making it straightforward to integrate with Arduino and other microcontroller boards.
The HC-06 module includes a built-in 3.3V voltage regulator, allowing for easy access to key pins (VCC, GND, TXD, RXD). Powered by the CSR BC4 chip and supporting Bluetooth V2.0 + EDR, it allows you to configure the baud rate, device name, and pairing password using AT commands when not connected to another Bluetooth device. As a slave module, it can be paired with Bluetooth master devices like computers, mobile phones, PDAs, and more, enabling seamless wireless communication in your projects.

China Quality HC-05 6pin Bluetooth Module (Slave) No Button Overview
The China Quality HC-05 6pin Bluetooth Module is a B-grade, slave-only wireless serial adapter (often referred to as HC-06 functionality) without an AT-mode button. It provides a simple UART interface (VCC, GND, TXD, RXD) for seamless data exchange between microcontrollers, PCs or smartphones over Bluetooth up to 10 meters.
Key Features of China Quality HC-05 6pin Bluetooth Module (Slave) No Button
- Slave-only Bluetooth 2.0/2.1 serial module (HC-06 equivalent)
- 6-pin PCB breakout with VCC, GND, TXD, RXD accessible for easy mounting
- Built-in 3.3 V regulator; input voltage 3.6 V–6 V (max 7 V)
- Low power draw: 30 mA unpaired, 10 mA paired
- Reliable range up to 10 meters in open areas
- Standard UART format: 8 data bits, 1 stop bit, no parity
- Fast shipping across India from Zbotic.in
Applications and Use Cases
- Wireless data link between Arduino/ESP boards and PCs or smartphones
- Remote control for robots, RC cars and drones via mobile apps
- Serial debugging and logging without USB cables
- Home automation sensor networks requiring simple BLE-like pairing
- Industrial machine monitoring where only slave pairing is needed
- Prototyping IoT devices that send telemetry to a master device
How to Use China Quality HC-05 6pin Bluetooth Module (Slave) No Button
Wire VCC to a 3.6–6 V supply, GND to common ground, TXD to your MCU’s RX pin and RXD to TX. Power on the module, then search and pair it from your smartphone or PC using the default PIN (usually “1234” or “0000”). Open a serial terminal or app at the matching baud rate (commonly 9600) and start sending and receiving data.

Frequently Asked Questions
Can I access AT-command mode on this module?
No. This B-grade module operates strictly in slave mode without an AT-button or KEY pin, so AT-commands are not accessible.
What voltage should I use to power the module?
Supply between 3.6 V and 6 V (never exceed 7 V). The onboard regulator provides the required 3.3 V for the Bluetooth chipset.
How do I change the communication baud rate?
This version comes with a fixed default baud (commonly 9600 bps). To adjust baud settings you would need a module with AT-mode support.
