HC-05 TTL Bluetooth Transceiver Module TTL OUTPUT (With Button)
Description:
The 6-Pin HC-05 Wireless Bluetooth RF Transceiver Module, available in a pack of 20, is an ideal Bluetooth module for Arduino projects. It enables wireless serial communication via the HC-05 Bluetooth transceiver, supporting the Bluetooth V2.0 protocol standard for secure connections with features like authentication and encryption.
The HC-05 module supports both master and slave modes, providing flexibility for various use cases. By default, it operates in slave mode, where it can accept incoming connections but cannot initiate them. However, users can easily switch between master and slave modes using AT commands. In master mode, the HC-05 can initiate connections with other Bluetooth devices, offering increased control and adaptability for wireless communication setups.
Wiring method:
- Power Supply (VCC): Connect the power supply positive.
- Ground (GND): Connecting the cathode.
- Receiver (RXD): The receiver, the Bluetooth module receives data from other devices, and the sending end TXD of the other devices normally.
- Transmitter (TXD): Send end, Bluetooth module sends data to other equipment; the receiving end RXD of the other equipment normally.
- Enable (EN): To enable the end, need to enter the at mode when 3.3V
Note: The module default baud rate is 9600, the default pairing password for HC-05 Bluetooth Module is 1234, while the default name is HC-05.
Applications:
- Can be used to with Arduino based projects.
- Can be used with android phones to control gadgets like Lights, motors, switches etc.

HC-05 TTL Bluetooth Transceiver Module TTL OUTPUT Overview
The HC-05 TTL Bluetooth Transceiver Module TTL OUTPUT (With Button) is a compact 6-pin wireless interface designed for direct TTL-level serial communication with microcontrollers and logic circuits. Equipped with a push-button for easy mode switching or AT-command entry, it supports both master and slave roles for flexible Bluetooth V2.0 connectivity.
Key Features of HC-05 TTL Bluetooth Transceiver Module TTL OUTPUT
- Direct TTL-level UART output for seamless interfacing with Arduino, STM32, ESP32 and other boards
- Master/slave operation switchable via built-in push-button and AT commands
- Default settings: 9600 baud, module name “HC-05”, pairing password “1234”
- Wide supply range 3.6 V–6 V; typical operating current ~50 mA
- Operates on 2.4 GHz ISM band using GFSK modulation, offering up to 10 m range
- Push-button for entering AT mode or toggling between communication roles
- Genuine HC-05 modules with fast shipping from Zbotic across India
Applications and Use Cases
- Wireless serial communication between Arduino-based robots and PCs
- Remote sensor data logging for home automation or environmental monitoring
- Bluetooth-enabled control of motor drivers, servos, or drones
- Serial debugging and firmware updates without physical USB connections
- Master mode scanning and pairing with multiple slave modules in mesh setups
- Hands-free data exchange between embedded devices and smartphones/tablets
How to Use HC-05 TTL Bluetooth Transceiver Module TTL OUTPUT
Connect VCC to a 3.6–6 V supply and GND to ground, then wire TXD to your microcontroller’s RX pin and RXD to its TX pin. To enter AT command mode for configuration, press and hold the onboard button while powering the module; release once the LED blinks slowly. Use a serial terminal at 9600 baud to change the name, password or role, then reboot without the button for normal operation.

Frequently Asked Questions
How do I switch the HC-05 between master and slave modes?
Enter AT command mode by holding the button during power-up. Then send “AT+ROLE=1” for master or “AT+ROLE=0” for slave via a serial terminal at 9600 baud. Reboot the module without the button to apply.
What is the effective wireless range of this module?
Under ideal, line-of-sight conditions, the HC-05 achieves up to ~10 meters. Obstacles like walls or interference can reduce this range.
Can I connect the HC-05 directly to a 5 V microcontroller UART?
Yes. The module’s TTL-level pins operate at VCC (3.6–6 V), so when powered at 5 V, its TXD and RXD are compatible with 5 V logic without additional level shifting.
