HC-05 Bluetooth Module Master-Slave 6-Pin creates wireless serial data bridges for Arduino Uno and IoT hardware. Operating in both master and slave modes, hardware connects controllers without external hubs. Under the v2.0+EDR standard, transparent UART links eliminate physical cabling.
Key Features
- Dual Mode Operation: Supports master and slave configurations via AT command sets. Removes the necessity for a central hub.
- Integrated 3.3V Regulator: Accepts 3.6V to 6V input via the VCC 6 pin pinout. Requires logic level shifters for 5V pins.
- Transparent Serial Link: Replaces physical RX/TX wiring with a v2.0+EDR wireless bridge. Simplifies serial communication in mobile robotics.
- Configurable Baud Rates: Supports 9600 to 460800 bps ranges through UART communication. Reduces latency in humid BD environments.
Frequently Asked Questions
What is the default password for HC-05?
Default pairing codes are 1234 or 0000. These credentials permit initial access during the discovery phase on Android apps.
Can HC-05 work as a master?
Yes, users configure master mode using specific AT commands. Master mode enables automatic connections to devices like the HC-06 module.
