Product Description

The module is powered by a 4.0V power supply that can deliver up to 2A of current. Care should be taken as any voltage over 4.5V would damage the module. The communication with this module is done through UART Interface. The data is sent to the module or received from the module through the UART interface. So you can communicate with your controller like Arduino, AVR, Raspberry Pi with just two wires.
