4.6.2 Ground and Power Wirings
One design its own board has to take care of the ground wiring and power wiring. The
power supply of the processor and additional signal conditioning components (e.g.
additional fast comparators, operational amplifiers) has to be decoupled from the
motor power supply. The ground connection has to be of low resistance and low
inductance to prevent against voltage drop and noise due to high currents. A ground
plane within a multi layer PCB is recommended for proper operation.
