ATtiny RS485 Quad Motor Control board is a AVR development board with 20 pin ATtiny2313 microcontroller along with Motor control and RS485 communication Ports. The motor control section contains two L293D chips and the RS485 communication section is build around the popular MAX485 chip from Maxim.

The Board is designed for controlling upto 4 DC brushed motors bidirectionally(Clockwise,Anticlockwise)

or 8 motors unidirectionally through a serial interface like UART or RS485 port.
