Raspberry Pi power supply and servo drive integrated module

Overview

This circuit integrates a servo controller and two sets of power management systems, and has the characteristics of compact size and high energy conversion efficiency. It supports up to 16 channels of servo control, 4.2V Raspberry Pi power input, and 5V-24V servo power supply. It has regular power supply mode and emergency power supply mode.
Conventional power supply mode. In this mode, the module is connected to two sets of batteries, which completely isolates the signal system power supply from the high-power power supply system, ensuring that the Raspberry Pi is not affected by the ripples generated by the high-power power consumption of the servo. Influence.

Emergency power supply mode: When the Raspberry Pi 4.2V power supply system displays low battery, the emergency power supply mode can be activated. The motor power supply system provides emergency power to the Raspberry Pi by connecting the upper pin header of the module.
