BIGTREETECH SKR 2

BIGTREETECH SKR 2 is a successor to the motherboards of the SKR 1.4 and SKR 1.4 Turbo series and has many new functions. This versatile 32-bit mainboard with a powerful 168 Mhz ARM-Cortex-M4 CPU is suitable for most 3D printers and offers many interfaces and upgrade options compared to most built-in motherboards.

The mainboard is compatible with RepRap and Marlin open-source software.

This version is the revised Rev B.

168 Mhz ARM-Cortex-M4 CPU

BIGTREETECH SKR 2 uses a 32-bit chip from the ARM Cortex-M4 series STM32F407VGT6 with a core frequency of 168 MHz, which offers enough power to serve even the most demanding user interfaces while enabling stutter-free printing.

AOZ1284PI-Power Regulator

The motherboard integrates an AOZ1284PI power regulator that supports a 12-24 V input and a maximum output of 4A - enough to operate external components such as LEDs and even a Raspberry Pi.
