HC05 Module is an easy to use Bluetooth SPP(Serial Port Protocol) module and it is designed for wireless serial communication applications. Thanks to it's pins coming out from the board, you can use it easily on breadboard with Arduino or your projects and you can prototype quickly. It supports master mode which the most of the bluetooth modules don't.
You can wire it to your circuits with the jumper wires sent together with the module.
This module supports Bluetooth 2.0 and it porvides a 10m communication range in open spaces and it communicates in 2.4GHz frequency. You can use it in hobby, robotic or academic projects.
Differently from HC06, HC05 can be used as master or slave.Features:
- Bluetooth Protocol: Bluetooth 2.0+EDR (Enhanced Data Rate)
- 2.4GHz Communication Frequency
- Precision: ≤-80 dBm
- Output Power: ≤+4 dBm
- Asynchronous Speed: 2.1 MBps/160 KBps
- Synchronous Speed: 1 MBps/1 MBps
- Security: Identity Validation and Encryption
- Operating Voltage: 1.8-3.6V(3.3V Recommended)
- Current: 50 mA
- Dimensions: 43x16x7mm
Note: RX ve TX pins are 3.3V logic leveled. If you wish to use it with Arduino or another 5V logic leveled systems, you can use the diagram below.
