HC05 Bluetooth DIP - Serial Module Card

HC05 Bluetooth Module can be connected to any device that supports the Serial Port Standard - SPP protocol and can be used in wireless communication projects. It is a Bluetooth V2.0 + EDR 3Mbps modulation with a 2.4GHz radio transceiver. It has a communication distance of 10 meters in open areas.

Can be configured as Master, Slave or Loopback modes. HC06 Bluetooth Module only in Slave mode available.

Other HC05 Bluetooth module, its pins are outside. In this way, connections can be made easily with jumper cables. It provides ease of use with breadboard and prototyping in Arduino projects.
