Servos & Power

Understand PWM, torque, voltage, and how to wire a stiff, brownout-resistant servo power rail.

• Explain hobby servo PWM pulse ranges (~500–2500 µs)

• Size a power supply for multi-servo stall currents

• Wire a common-ground architecture safely

• Add bulk capacitance and observe voltage sag under load
