This is a great STM32 based 32-bit printer motherboard compatible with Klipper and a wide range of printers.
It has built-in TMC2209 drivers, can support 24V, and has enough power capabilities not to require any external mosfet for powering a heated bed.
Condition: Used but TESTED - this was recently pulled from a known working printerAlready has latest version of the Klipper MCU firmware installed just the other day.
