This tutorial investigates whether a 9g 360° servo motor can be powered directly from the Nano Dev Board without external supply. Using detailed current and voltage measurements under start-up, steady-state, and stall conditions, the results show the Nano Flip’s onboard regulator and USB-C path can safely handle the current draw without voltage sag below 4.96 V. Both USB-C and Vin configurations were tested with consistent stability. While this approach is suitable for short tests and educational use, long-term or production designs should still employ a dedicated power supply for servos to ensure reliability and isolation from the microcontroller rail.
