Description
480Mhz ARM Cortex-M7
BIGTREETECH SKR 3 EZ uses a 32-bit ARM Cortex-M7 series STM32H743VI chip with a core frequency of 480MHz, providing enough performance to handle even the most demanding user interfaces while enabling stutter-free printing.
Higher Motor Driver Voltage - Faster print speeds
The motor driver voltage of up to 48V can be set using jumpers. However, 48V is only supported when using TMC5160 Pro drivers.
