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

Description

SKR 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) 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; 5) The special function interface uses conspicuous pin headers, which greatly reduces the error rate of wiring. 6) Reserved I2C, SPI, WIFI interfaces, convenient for customers to DIY; 7) Reserved closed-loop drive interface, eliminating the trouble of plug-in transfer module; 8) Dual Z-axis interface, eliminating the trouble of external drive expansion module; 9) The thermistor interface is protected by a bile capacitor pressure sensitive resistor to enhance the resistance of the interface; 10) More fan interfaces: 1 digitally controlled fan, 3 normally open fans; 11) External DC5V power module can be plugged in to supply power to TFT screen, BLtouch. Potentiometer Setting Instructions: Turn Potentiometer Clockwise - Reduce Vref to Reduce Drive Current Turn Potentiometer Counterclockwise - Increase Vref to increase drive current If the motherboard provides 12V or 24V, the exact voltage of Vref can be measured. Range of Vref values: Default value: 1V (± 0.2); MAX: 2V; MIN: 0 V;Do not apply excessive force when turning the potentiometer to prevent irreversible damage to the potentiometer. When the potentiometer rotates counterclockwise to its maximum value, it becomes the minimum as it continues to rotate as it is turned clockwise to the minimum. If you keep turning, the maximum value will be displayed.
