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.

If you are designing a PCB or Perf board with this component then the following picture from the IRF740 Datasheet will be useful to know its package type and dimensions.You can find a complete review with detailed features of our electronics in Spanish and English on 3dwork.io. It is relatively cheap and has very low thermal resistance, added to this the mosfet also has good switching speeds and hence can be used in DC-DC converter circuits. The Mosfet requires a driver circuit to provide 10V to the gate pin of this Mosfet the simplest driver circuit can be build using a transistor. Hence this mosfet cannot be used in applications where high switching efficiency is required. One considerable disadvantage of the IRF740 Mosfet is its high on-resistance (RDS) value which is about 0.55 ohms. If you prefer a mosfet with low gate voltage then try IRF540N or 2N7002 etc. Since the mosfet is for switching high current high voltage loads it has a relatively high gate voltage, hence cannot be used directly with a I/O pin of a CPU. The Mosfet could switch loads that consume upto 10A, it can turned on by provide a gate threshold voltage of 10V across the Gate and Source pin. The IRF740 is an N-Channel Power MOSFET which can switch loads upto 400V. Note: Complete technical details can be found at the IRF740 datasheet linked at the bottom of the pageīSS138, IRF520, 2N7002, BS170, BSS123, IRF3205, IRF1010E
