BIGTREETECH SKR V1.4 Turbo Control Board 32bit for 3D Printer Compatible with TFT35 E3 V3.0.1/TFT70 Touch Screen Support TMC2209/TMC2208/TMC5160/TMC2130 for Most FDM 3D Printer (with 5*TMC2209)

Key features

• ✨BIGTREETECH SKR V1.4 Turbo using 32-bit 120MHz ARM-class Cortex-M3 series LPC1769 main control chip, the performance is greatly improved.
• ✨SKR V1.4 Turbo control board can supply power to TFT screen, BLtouch, Neo-pixel by plugging in an external DC5V power module; in addition, I2C, SPI, WIFI interface is reserved to facilitate customer DIY.
• ✨On-board TMC-driven SPI working mode and UART working mode, and the on-board DIAG function pins are convenient for customers to use, eliminating the complicated wiring process, which can be used by simply removing and inserting the jumper cap.
• ✨Compare to other stepper motor driver in the market, our TMC2209 silent stepper driver generate lower heat and it has a large-area cooling position to lower the temperature. It driver can lower 30% heat than others stepper motor drivers even working last for a long time. With Passive cooling on a 10 hours print, they only hit 37℃.
• ✨BIGTREETECH TMC2209 V1.2 is an ultra-silent motor driver IC for two-phase stepper motors, which adopts stealthChop2 Mute technology which reduces motor noise to the point of silence at low velocities to ensures noiseless operation, maximum efficiency and best motor torque. spreadCycle allow for highly dynamic motion. Drive current 2A, peak current 2.8A, voltage range 4.75V-29V, 256 subdivision.
