Expansion port: BLTouch(Servos, Probe), PS-ON, PWR-DET, Fil-DET, RGB, FDCAN.
Overall max current(HB+E0+E0+All fans): 10A.Selectable voltage (24V, 12V, 5V by SKR 3-DC MODE)for CNC fan (Note: The voltages of the 3 * CNC fans are unified, different voltages cannot be set separately for different ports), no more need for external stepdown.Fan port: 3 X CNC(selectable voltage), 2 X always on(PSU voltage), max current: 1A per port.Thermistor connection supports Pull up resistance value(1Kohm) setting using jumpers, No more extra module needed for PT1000(Accuracy is much lower than max31865).Thermistor circuit is protected to prevent MCU damage from shorted heatbed and heater cartridge connection.Heated bed(HB) max current: 10A, heater cartridge(E0, E1) max current: 5.5A.DCDC 5V current output rated at 5A max continuous and 6A max instantaneous.MCU: ARM Cortex-M7 STM32H743VI 480MHz with FDCAN bus.You can find a complete review with detailed features of our electronics in Spanish and English on 3dwork.io.
