README
README.mdesp2400
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.
its main functions include: . 0-50.00V and 0-50.00A output with internal 14bits resolution . Multi-points calibration of voltage and current. . Two EC11 rotaries to control voltage and current separately . Multi quick-pick of voltage and current by single pressing button . Statistics by seconds, minutes, hours . WIFI STA and AP support with a simple web view for remote control . Command line support with USB-Serial interface (also firmware updating interface) . Temperature controlled FAN output using PID algorithm . A discharging circuit to decrease dormancy of switching power supply at low-voltage outputing . Rate of rising and falling of voltage and current can be controlled . Chinese and English bundles support (but in fact, original ZXD2400 with its PFC circiut can be used in AC220V zones)

Questions
How big is the Esp2400 PCB?
It measures 81.1 × 27.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp2400 use?
110 parts, built around the CH340C, GS8552-SR, CS1237-SO and XL2001E1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Esp2400 KiCad files?
From the m24h/esp2400 repository on GitHub, at the commit this page was made from: the board is hardware/esp2400.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp2400 design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
