BIGTREETECH SKR V1.4 Turbo 32bit Controller Panel Board for 3D Printer Compatible With12864LCD/ TFT24 Support 8825/TMC2208/Tmc2130 (with 5TMC2209)

If the SD card does not work, or other problems, please contact us through store, we have a professional after-sales support team, we provide you with 24-hour service motherboard features: 1) Adopt high-performance MOSFET tube, better heat dissipation effect; 2) The use of pluggable fuses makes the replacement process easier; 3) Reserve BLTouch interface SERVOS and Probe for easy use of BL Touch; 4) RGB light bar supporting scheme; 5) Use the power selection design to separate the USB power supply from the switching power supply, effectively avoiding short circuit Causes the computer’s USB port to be burned; 6) The special function interface uses conspicuous pin headers, which greatly reduces the error rate of wiring. 7) Reserved I2C, SPI, WIFI interfaces, convenient for customers to DIY; 8) Reserved closed-loop drive interface, eliminating the trouble of plug-in transfer module; 9) Dual Z-axis interface, eliminating the trouble of external drive expansion module; 10) The thermistor interface is protected by a bile capacitor pressure sensitive resistor to enhance the resistance of the interface; 11) More fan interfaces: 1 digitally controlled fan, 3 normally open fans; 12) External DC5V power module can be plugged in to supply power to TFT screen, BLtouch, . The TMC2209 is an ultra-quiet two-phase stepper motor driver chip with a continuous drive current of 2A and a peak current of 2.8Aared to the TMC2208, the drive current is improved by 0.6A–0.8A, while the Blockage increases the stall detection functionides up to 256 segments;stallguard4TM stall detection, which can feed back an abnormal signal when the motor rotates abnormally Coolstep current dynamic adjustment, saving 75% of energy.
