HC-05 6 Pin Wireless Serial Bluetooth Module is a Bluetooth module for use with any microcontroller.  It uses the UART protocol to make it easy to send and receive data wirelessly. The HC-05 Wireless Bluetooth Module without Baseplate is a slave only device.  This means that it can connect to most phones and computers with Bluetooth but it cannot connect to another slave-only device such as keyboards and other HC-06 modules.  To connect with other slave devices a master module would be necessary such as the HC-05 version which can do both master and slave. We also stock HC-05 Module with base plate. Applications: Embedded Projects. Industrial Applications. Computer and Portable Devices. GPS receiver.
