BIGTREEETECH SKRat V1.0 Control Board
The BIGTREETECH BTT SKRat V1.0 Control Board is a compact, high-performance 32-bit motherboard developed in collaboration between BIGTREETECH and Rat Rig. Optimized for RatOS and Klipper firmware, it delivers smooth, fast, and precise control for modern 3D printers, especially Rat Rig builds and custom Klipper setups.
Key Features:
- Powerful MCU: 32-bit 64 MHz ARM Cortex-M0+ STM32G0B1VET6 processor for reliable real-time performance.
- 5-Axis Support: Drives up to 5 stepper motors with integrated SPI and UART modes for TMC drivers (DIAG pin accessible via jumpers).
- Modern Connectivity: Built-in CAN Bus support, UART and I2C expansion ports, plus compatibility with Raspberry Pi (CM4 / CB1) for full RatOS experience.
- Rich Interfaces: Supports BLTouch, filament runout sensor, power loss recovery, auto power-off, MAX31865 PT100, ADXL345 accelerometer, RGB, and multiple fan headers (2-pin & 4-pin).
- Compact Design: Mounting size 110 × 85mm – ideal for space-constrained builds like V-Minion or small Rat Rig printers.
- Easy Bootloader Update: Onboard BOOT button for DFU mode.
This board is the perfect choice for users running RatOS on Rat Rig printers or anyone building a fast, quiet, and feature-rich Klipper machine. It offers excellent expandability and silent printing when paired with TMC drivers in UART or SPI mode.
