E&OE Overview This motor driver board, originally designed by Dagu for their Rover 5 platform, is ideal for any small 4-wheel drive robotic vehicleWith four motor outputs, four encoder inputs and current sensing for each motor, it's a must-have when implementing omni or mechanum wheelsThe motor drivers can be controlled by simply applying a logic 0 or 1 to the direction pin for that motor and a PWM signal to the speed pinIn this way, the speed and direction of four separate motors can be controlled independently from only 8 GPIO pinsThe encoder inputs on the driver board mix each pair of encoder inputs using an XOR gate making it possible to read both inputs from a quadrature encoder using only one interrupt pinReading the current sensor output is easy, each current sensor pin will output about 1V for each Amp of current drawn by the associated motor up to 5VConnect the current sensor pin to the analog input of your controller and you'll be able to detect stalls and other motor problemsThere are two power connectors on board : One is for 5V logic and the other is the Motor SupplyBe sure to turn on your logic supply before applying the power source for your motorsThe board is rated for a maximum motor supply voltage of 12V Features 4 x Low Resistance FET “H” BridgesEach Channel Rated for 4A Stall CurrentEasy-to-Use Control LogicCurrent Monitoring for Each ChannelQuadrature Encoder Mixing Circuitry Downloads Instruction Manual - 4 Channel 4.5A Motor Control Board PDF File 1.42 MB
