BIGTREETECH SKR 3 EZ is a high-performance motherboard compatible with the new EZ drivers. The motor driver voltage of the new SKR 3 EZ can also be adjusted from 24V to 48 volts using jumpers. The motherboard is compatible with Klipper, RepRap and Marlin open-source software. Highlights: 32-bit MCU 480Mhz ARM Cortex-M7 Compatible with EZ drivers
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.
