| | 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.| | | Extruder heater | 1 x Screw terminal | OUT_0 | High current output intended for extruder heater, maximum current 5A, this is VIN voltage only.

| | Extruder fan | 4-pin JST PH | OUT_1 | 4-wire fan output (also accepts a 2- or 3-wire fan) intended for use as the print cooling fan. 2A total max current for OUT1 and OUT2 when VIN selected (v1.1 board), 0.8A total max current for OUT1 and OUT2 on 12V. This output is protected by a flyback diode. Note On v1.0 boards and earlier, VOUT on OUT_1 and OUT_2 is set to 12V. On v1.1 boards, voltage is selectable between 12V and VIN, using VOUT for OUT_1, OUT_2 pins. Note When using a 4-wire fan, the tacho reading is valid at all PWM settings. | | | Extruder fan | 4-pin JST PH | OUT_1 | 4-wire fan output (also accepts a 2- or 3-wire fan) intended for use as the print cooling fan. 2A total max current for OUT1 and OUT2 when VIN selected (v1.1 board), 0.8A total max current for OUT1 and OUT2 on 12V.
