If bigger motors with higher peak currents need to be controlled, 4 buffer capacitators (e.g. 47uF, 50V) can be aditionally soldered to the bottom layer of the pcb.

The 2 dc servos can be protected by an adjustable current limiting circuit, which is seperate for each moter and based on a standard current source circuit around a comparator opamp, shunt and mosfet. The reference current can be adjusted by 1 poti and is about 10 - 100mV.
