### Thermistor / PT1000
### Thermistors / PT1000

JST-PH 2 mm connectors. The thermistor input has a 2.2KOhm pullup resistor to allow for better resolution when using a PT1000 sensor.

### Hotend heater

Max 4A. Enough for a 100W heater when running on 24V

### Endstop

The endstop supplies 3.3V to work with an optical endstop sensors. For a microswitch (NO) connect it to GND and Signal.
Please note that klipper at the moment requires an endstop to be on the same board as the stepper driver. If the board is used for an extruder the endstop can not be used for a bed probe. The endstop can be used as a filament runout on a hotend, or as an axis endstop if the board is used for movement.
The endstops supply 5V to work with an optical endstop sensors. For a microswitch (NO) connect it to GND and Signal.

### CAN bus

Power and CAN bus in in the same Molex MicroFit connector.
There is no on board CAN bus termination resistor.
There is an on-board CAN bus termination resistor soldered in place.

### LED
