Four-axis 3D printer control board based on rp2040zero

Overview

Mini 4-axis 3D printer control board (klipper firmware) based on rp2040-zero development board, 54*98mm, I have recently become obsessed with this size, it feels small and cute, although it is small, it has all the internal organs, four-axis full uart, onboard rgb (gpio16 ), 3 limit support voltage selection 3v3/input voltage (via solder pad tinting method), motor drive power supply voltage selection 3v3/5v (via soldering pad tinning method) to solve the problem of low current of 3v3 power supply a4988, high voltage part double The fuse can be selected according to needs. It is recommended that the voltage input is 10a, and the heating bed part is 7.5a. The input interface is designed with ESD protection, and welding can be selected according to needs.
