PandaZHU use ESP32 as the MCU of motherboard for 3D printer.
while PandaM4 is designed for drop in Creality ender printer.

Powerful:

it has larger memory and more powerful than normal 32bit motherboard.Two 240MHz MCU,4MB memory
support 8 motor drivers and three heaters with one fast expand GPIO chip.
the speed of uploading gcode file is 10 times faster than it as a wifi module.
play music(mp3/wav) when printer boot or printing finished...
Easy to use:

upload marlin firmware through wifi with browser.
upload gcode file, configure printer and control printer wireless with browser.
