The breakout PCB breaks out the 14pin toolhead cable into individual ports that can then be connected to the mainboard. The breakout PCB has ports that correspond to their counterparts in the toolhead PCB. The breakout PCB also accepts a 4 pin endstop cable.
The table below briefly describes the purpose of each port located on the breakout PCB.
|HEF/24V||Hotend Fan*||JST-XH-2P||Fan port for cooling the hotend heatsink. HEF denotes the negative pin.|
|PCF/24V||Part Cooling Fan*||JST-XH-2P||Port for part cooling fan. PCF denotes the negative pin.|
|HE0/24V||Hotend Heater*||Microfit3-2P||Port for hotend heater cartridge. HE0 denotes the negativepin.|
|TH0/GND||Hotend Thermistor||JST-XH-2P||Thermistor port for hotend. TH0 denotes the signal pin.|
|CT/GND||Chamber Thermistor||JST-XH-2P||Thermistor port for the onboard thermistor on the toolhead PCB. CT denotes the signal pin.|
|XES/GND||X Endstop||JST-XH-2P||X endstop port. XES denotes the signal pin|
|YES/GND||Y Endstop||JST-XH-2P||Y endstop port. YES denotes the signal pin|
|Vin/X/Y/GND||Input for the Endstop PCB||JST-XH-4P||The input port from the endstop PCB used in V2.4 or Trident. If a hall endstop PCB is used, extra circuit on the PCB needs to be populated to generate 5V at Vin. This port is not used in Switchwire builds.|
|E-MOTOR||E Stepper Motor||JST-XH-4P||Extruder stepper motor port|
|CFAN/24V||Chamber Fan**||JST-XH-2P||Connects to the electronics chamber fan in the switchwire. CFAN denotes the negative pin.|
|LED/24V||LED**||JST-XH-2P||Connects to the LED strip in the switchwire. LED denotes the negative pin.|
|CFAN/LED||Chamber Fan + LED Control Signal**||JST-XH-2P||Connects to the LED/CFAN control signals on the mainboard. Only used in Switchwire.|
