294.2.2 Motor BoardFor the motor board, the circuit consists of the UCN5804 unipolar steppermotor driver, connectors to the main board and stepper motor, power resistor, diodesand capacitors. The main task for the motor board is to receive signals from the mainboard and send to the motor to control the movement of the robot. The view of themotor board is shown in Figure 4.4 while the schematic diagram for the motor boardis shown in Figure 4.5.Figure 4.4 Top View of Motor Board
