BIGTREETECH SKRat V1.0 control board is a high-performance 32-bit motherboard designed for modern 3D printers running Klipper firmware and RatOS systems.
Developed in collaboration with Rat Rig, it provides stable, fast and precise motion control for advanced printer builds.
It supports multiple stepper drivers in UART and SPI mode, making it compatible with TMC series drivers for smooth and quiet operation.
Key Features:
- 32-bit STM32G0B1 MCU for stable real-time control
- Optimized for Klipper / RatOS systems
- Supports TMC stepper drivers (UART / SPI mode)
- Built-in CAN bus interface for expansion
- Multiple fan voltage control options
- Supports BLTouch, filament sensor, power loss recovery
- Compact design for space-efficient builds
