Are you looking to buy an LDO ToolHead PCB and Breakout Board kit in Australia?
This Kit includes 1x Breakout board. Cables can be found here
The Toolhead Cable
The toolhead cable is a cable designed to be carried through the gantry cable chains within Voron printers. All individual wires within the cable are UL1332 high strand count cables. UL1332 wires have durable FEP insulation to reduce friction between the wires and cable chain. The high strand count helps prevent breakage with repeated bending cycles.
Caution! The zipties that come with the cable must be removed prior to installation into the cable chains. These zipties are used to prevent tangling during shipping, however, they can get caught within the cable chain and can cause damage if not removed.
The Breakout PCB
The breakout PCB serves the opposite purpose of the toolhead PCB - it breaks out the 14pin toolhead cable into individual ports that can then be connected to the mainboard. The breakout PCB have ports that correspond to their counterparts in the toolhead PCB. The breakout PCB also accepts the 4 pin endstop cable included in LDO kits.
Port Descriptions
The table below briefly describes the purpose of each port located on the breakout PCB.
| PCB Label | Name | Connector | Description |
| 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 negative pin. |
| 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. |
| 24V/ABL/GND | Probe | JST-XH-3P | Probe port. |
| 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. |
*Caution! Note that polarity matters when making connections between the breakout PCB and your mainboard. Incorrect polarity can cause a short circuit and destroy your mainboard!
**Only used in Switchwire builds.
Unpopulated Circuitry on the Breakout PCB
The breakout PCB contains two circuits that may or may not be populated:
- Mosfet circuit for CFAN/LED. This circuit is only populated for breakout boards supplied in Switchwire kits.
- 5V power supply circuit. This circuit generates a small 5V supply the Vin pin for those that wish to use the Hall Endstop PCB. If you wish to solder this circuit yourself, check the circuit below. Note that this circuit is not designed for high current loads and should only be used to power the hall endstop PCB.
| Breakout Board 5V circuit | ||
| Ref | Item | Form Factor |
| U1 | 7805 Voltage Regulator | SOT-89 |
| C3 | 330NF, 50V Capacitor | 0603 |
| C4 | 100NF, 50V Capacitor | 0603 |
