HC-05 6pin Bluetooth Module with Button

From the shop's description

HC-05 6pin Bluetooth Module with Button 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-06 module 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. Applications: Embedded Projects. Industrial Applications. Computer and Portable Devices. GPS receiver. Features: Working current: matching for 30 mA, matching the communication for 8 mA. Dormancy current: no dormancy. Used for a GPS navigation system, water, and electricity gas meter reading system. With the computer and Bluetooth adapter, PDA, seamless connection equipment. Bluetooth module HC-08 Master and slave Two in one module. Use the CSR mainstream Bluetooth chip, Bluetooth V2.0 protocol standards. Potter default rate of 9600, the user can be set up. Bluetooth protocol: Bluetooth Specification v2.0+EDR Speed: Asynchronous: 2.1Mbps(Max) / 160 kbps, Synchronous: 1Mbps/1Mbps. Security: Authentication and encryption. Profiles: Bluetooth serial port.
