This is a PCB made for Armchair Engineering's Xol Toolhead, featuring:
- One hotend cooling fan JST-XH connectors with diode for tach signal
- Two part cooling fan JST-XH connectors
- One heater Micro-Fit connector
- One thermistor Micro-Fit connector
- One Neopixel JST-XH connector with resistor for the data line
- Two auxiliary JST-XH connectors
- One extruder motor connector
- Selectable fan voltage (5V, Alt, 24V)
- Integrated mount for carriage screw
I customized the Xol Toolhead board by ruiqimao to suite my needs:
- A three pins connector for the hotend fan with tach signal and its diode
- A resistor for the RGB data line to avoid signal noise for the cable length
- Three AUX pins for X-endstop and the two filament sensors
ATTENTION! This pcb isn't pin compatible with ruiqimao one starting from the main connector (from 16 to 18 pins). Even the thermistor and hotend connectors are swapped. Check carefully the pinout!

Pinout
From the point of view looking directly at the wiring harness connector:
| Pin | Usage | Pin | Usage |
|---|---|---|---|
| 1 | Neopixel | 10 | Auxiliary 2 |
| 2 | Part cooling fan ground | 11 | Auxiliary 3 |
| 3 | Hotend fan ground | 12 | Alt voltage |
| 4 | Thermistor ground | 13 | Thermistor |
| 5 | Motor A1 | 14 | Motor B1 |
| 6 | Motor A2 | 15 | Motor B2 |
| 7 | Ground | 16 | Hotend fan tach |
| 8 | 5V | 17 | Auxiliary 1 |
| 9 | Hotend voltage | 18 | Hotend ground |
Selectable fan voltage
There are two sets of solder jumpers, one for each type of fan, that should be bridged to select the fan voltage.
Extruder compatibility
The PCB and strain relief are designed with only the Sherpa Mini in mind. Usage with other extruders may require the motor connector to be swapped to the back side.

Questions
How big is the Xol PCB PCB?
It measures 51.4 × 46.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Xol PCB use?
21 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Xol PCB KiCad files?
From the valepe/Xol_PCB repository on GitHub, at the commit this page was made from: the board is KiCad/xol-pcb.kicad_pcb and its schematic KiCad/xol-pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Xol PCB design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
