with thermistor protection circuitĤ.7KOhm 0.1% pull up resistor for NTC100K,etc. 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)
