Duet 3 Toolboard 1LC
OUT_0, OUT_1 and OUT_2 are PWM-capable
| My mod | Connector (board revision) | Label | Function |
| 4-pin JST PH | IO_0 | Input/output with +5V power, for endstops, Z-probes. Input is 30V-tolerant | |
| 3-pin JST PH | IO_1 | Input/output with +5V power, for endstops, Z-probes. Input is 3V-tolerant | |
| . | 3-pin JST PH | IO_2 | Input only with +5V power, for endstops or tool pickup detection switch. Input is 30V-tolerant |
| 1 x 3-pin footprint | IO_3 | (v1.1 board) Footprint to mount an Omron D2FD-1L30-1T ultra subminiature switch or similar. In v1.2 and v1.3 the footprints for an ITR20001/T or TCRT1000/1010 reflective optical sensor are also added.Example use case is a tool docking confirmation switch. | |
| Extruder motor | 4-pin JST PH | DRIVER_0 | Stepper motor connection |
| Extruder thermistor | 2-pin JST PH | TEMP_0 | Thermistor or PT1000 input. TEMP_0 uses a 16-bit ADC for high resolution reading of PT1000 sensors |
| 2-pin JST PH | TEMP_1 | Thermistor or PT1000 input | |
| Extruder heater | 1 x Screw terminal | OUT_0 | High current output intended for extruder heater, maximum current 5A, this is VIN voltage only. There is no flyback diode on this output, so if you connect a high-current inductive load, you must use an external flyback diode. |
