S4.7A bidirectional brushed ESC

Overview

Using the simplest few components, we made a 7A bidirectional brushed ESC.

Finished product

This ESC uses STC15W104 as the main control chip, which provides 1A BEC capability and can support up to two 9g servos. If you want to use a larger current, please connect a separate external power supply. The motor driver chip uses 7886, with a maximum of 13A and a continuous duration of 7A, which can be used as an option for toy cars.
