BigTreeTech SKR 3 EZ 32-Bit Motherboard
This is the EZ version of the new SKR3 board. This is equipped with slots for the new EZ drivers from BigTreeTech. But can also be used with normal TMC drivers.
Powerful mainboard that supports up to 5 stepper drivers and with a faster 480MHz CPU.
Thanks to the 32-bit ARM Cortex M7 processor, this board can perform more arithmetic processes than the standard 8-bit boards that are built into most 3D printers.
This allows you to use more demanding software such as Marlin 2.0 and Klipper.
It is the successor to the SKR 2 motherboard and adds many new and improved features.
