Open source CAN bus hub designed to work with Deutsch DTM plugs for automotive usage. The off the shelf version of these hubs cost significantly more than to make one using these PCB, so this is a budget way for enthusiasts and DIY'ers to save some money. This project has been fully open sourced. All files and instructions for assembly and completion will be located on Codeberg.

Features:

1. Alignment for Deutsch DTM 4 pin plugs. Just solder in your pins and plug them in!
2. Location for termination resistor. No need to rely on your components to have the termination resistor. You can solder it into any board you would like.
3. Edge connection for soldering. No need to add wires. Just solder the bridge between each PCB.
4. Relatively high current capacity. Each board can handle roughly 10amps passing through and each pin can handle roughly 7amps (the limit of the DTM pins). This means your entire hub can handle 10amps total and 7amps max per plug.
5. Link ECU pinout. This should also work for Haltech and others. The Github link has more information on the pinout.
