Product description: DFRobotDRV8825 - two-channel stepper motor controller 45V/2.5A - Shield for Arduino.

It is a cartridge for Arduino that allows to control twostepper motorsthrough the popularDRV8825 system.On the board there is a socket for connecting XBee wireless modules and clamp connectors for easy connection of motors.

One pulse given on the STEP pin causes one step of the motor in the direction chosen by giving the appropriate logical state on the DIR pin. The STEP output of the controller no. 1 has been connected to D5 Arduino, DIR to D4 pin. The STEP output of the controller no. 2 to pin D6 and DIR to D7.
