HC-05 TTL Bluetooth Transceiver Module (Without Button)

The HC-05 is a versatile, low-cost Bluetooth transceiver module that facilitates wireless serial communication between devices. It operates using the TTL (Transistor-Transistor Logic) protocol and is designed to allow seamless data transfer for a variety of embedded systems and microcontroller applications. This particular version of the HC-05 does not include a physical button for mode selection, making it suitable for integration in projects where space and simplicity are prioritized.

Applications:

• Wireless Communication: Establishing wireless serial communication between microcontrollers, computers, and other devices.
• Home Automation: Integrating into home automation systems for controlling devices wirelessly.
• Robotics: Enabling remote control and data exchange in robotic applications.
• Health Monitoring Systems: Facilitating wireless data transmission in wearable and portable health monitoring devices.
• Industrial Automation: Implementing in industrial environments for wireless control and monitoring of machinery and equipment.

Pin Configuration:

• VCC: Power supply (3.6V to 6V)
• GND: Ground
• TXD: Transmit data (connected to the RXD pin of the microcontroller)
• RXD: Receive data (connected to the TXD pin of the microcontroller)
• State: Output pin to indicate the connection status
• EN: Enable pin (used to set the module in AT command mode)
