The BIGTREETECH SKR V1.4 / SKR V1.4 Turbo is a popular 32-bit silent control board designed as a high-performance upgrade for FDM 3D printers. It builds on the success of the SKR V1.3 with improved features, better expandability, and a faster Turbo version featuring the LPC1769 MCU (120MHz) compared to the standard LPC1768 (100MHz).
Key Features:
- 32-Bit High-Performance MCU — Standard SKR V1.4 uses LPC1768 (100MHz); Turbo version uses LPC1769 (120MHz) for ~20% faster processing and smoother operation.
- Silent Stepper Drivers — Supports TMC2209, TMC2226, or other socketed drivers for ultra-quiet printing with sensorless homing capability.
- Rich Interfaces — Dual Z-axis ports, TFT35 / TFT43 / TFT70 touch screen support, filament runout, power loss recovery, RGB LED, and multiple expansion options (WiFi, BLTouch, etc.).
- Improved Design — Better heat dissipation, more stable power design, and additional ports for modern upgrades.
- Firmware Support — Excellent compatibility with Marlin and Klipper firmware.
Note: The SD card is not included.
