From the project
A digitalizing power supply control board woking with modified ZXD2400 (50V 50A) modoule
A digitalizing power supply control board woking with modified ZXD2400 (50V 50A) modoule.
This project is a control board mainly using ESP32 as core MPU, with ST7789V display, including software source codes, hardware design, and other parts design, to control a simply modified ZXD2400 power supply module.
In fact, this project is suitable for modifying other power supply module too.
