Description
BIGTREETECH SKR 3 is a successor to the SKR 2 and has many new functions. This versatile 32-bit motherboard with powerful 480 Mhz ARM Cortex-M7 is suitable for most 3D printers and offers many interfaces and upgrade options compared to most built-in motherboards.
The motherboard is compatible with Klipper and Marlin open-source firmware.
480Mhz ARM Cortex-M7
BIGTREETECH SKR 3 uses a 32-bit ARM Cortex-M7 series STM32H743VIT6 chip with a core frequency of 480MHz, providing enough performance to handle even the most demanding user interfaces while enabling stutter-free printing.
DIY friendly
- BOOT0 facilitates DFU mode to flash firmware
- The upgraded thermistor input now requires no external module for P1000
- A universal WiFi modular port allows the use of RRF firmware
