BTT SKR 2 - Control Board

BIGTREETECH SKR 2 is the successor to the SKR 1.4 and SKR 1.4 Turbo control boards and has many new features. This universal 32-bit control board with a powerful 168 MHz ARM-Cortex-M4 Processor is suitable for most 3D printers and offers many interfaces and upgrade options compared to most built-in control boards.

The control board is compatible with open-source firmwares RepRap and Marlin.

ARM-Cortex-M4 168 MHz Processor

The BIGTREETECH SKR 2 uses a 32-bit chip from the ARM Cortex-M4 STM32F407VGT6 series with a core frequency of 168 MHz, which offers enough power to handle even the most demanding user interfaces and allows for jam-free printing.

AOZ1284PI DC/DC Converter

The control board integrates the AOZ1284PI converter, which supports 12-24 V input and a maximum output current of 4A, which is sufficient for powering external components such as LEDs and even a Raspberry Pi.
