And the fan that connects to the harness with the 5-pin connector isn't wired to the 5th pin(it doesn't look like there's even a pin in the 5th hole). Since it looks like all three fans are 4-wire 12V fans(same part numbers even). I don't quite get why one of the fans is connected with the 5-pin connector. Or, rather, that it has two 4-pin fan connectors, and one 5-pin fan connector. Which in turn connects to two 4-pin fans, and one 5-pin fan. with thermistor protection circuitĤ.7KOhm 0.1% pull up resistor for NTC100K,etc.It looks like the 6-pin connector is for(what we call in automotive terms) a wiring harness. 1KOhm(SKR 3) or 2.2KOhm(SKR 3 EZ) 0.1% pull up resistor for PT1000 by jumper. Is converted to 5V to MOSFET with flyback protectionĤ.7KOhm 0.1% pull up resistor for NTC100K,etc. SKR 3 EZ is converted to 5V to driver (SKR 3 is MCU 3.3V) All other parameters are the same as SKR 3.High and low voltage can be selected for all stepper driver by jumper.Logic voltage: Stepper driver signal DC 5V.Thermistor connection supports Pull up resistance value(2.2Kohm, SKR 3 use 1Kohm, Within our working temperature range, the voltage change scale of 2.2k with PT1000 is more obvious, and the temperature collected under the same ADC accuracy is more accurate than 1K) setting using jumpers, No more extra module needed for PT1000(Accuracy is much lower than max31865).Supported Firmware: Marlin, Klipper and RRF(RepRapFirmware).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.
