ESP32Cube

This article presents an MCU-controlled single-button power switch circuit using a hardware-software hybrid approach. It employs a P-channel MOSFET (V1) as the main power switch, an N-channel MOSFET (V2) with MCU GPIO for state latching, and two diodes (D1, D2) for power-on control and shutdown detection. The circuit features simple structure, minimal components, low cost, and remote shutdown capability, suitable for 3.3V or 5V portable electronics.

A complete guide to the L298N DC motor driver module, covering pin descriptions, power supply configurations, speed control with PWM, and wiring examples for use with Arduino or ESP32.
