105c rated AWD splitter pcb for 3d printers
I needed a simpler way to wire up AWD printers, so I decided to make a simple AWD splitter PCB. instead of running 12 sets of wires, 4 for motors and 8 for fans and thermistors, this means you only need to run two big 16 channel wires down to your electronics bay. On the other end of the big wires, you can just use another one of these PCBs to break it back out and connect it to your mainboard, or just crimp individual connectors on the other end. This supports four motors for AWD, as well as a thermistor and cooling fan for each. It is rated to 105c chamber temps (limited by the connectors) but could likely go higher if needed.
To use this project, solder the connectors onto the top side of the board. Crimp your motor wires and plug them into the motor ports. Take a 16 pin connector and wire it down to your electronics bay. Do the same for the thermistors and fans if desired.
The PCB itself is very simple, but I tried to keep it fairly compact so it can fit easily anywhere on a printer. It uses Molex Nanofit connectors for high temp resistance and ease of crimping.

Questions
How big is the Awd splitter PCB?
It measures 28 × 72 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Awd splitter use?
16 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 Awd splitter KiCad files?
From the 2Mon/awd-splitter repository on GitHub, at the commit this page was made from: the board is PCB/awdsplitter.kicad_pcb and its schematic PCB/awdsplitter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Awd splitter design in my own project?
Its repository states no licence, so its author keeps all rights: ask 2Mon before reusing the design.
