This list of hardware parts focuses on Mouser part numbers, as the most commonly used online electronics store. You can of course get the manufacturer’s part number from there and buy elsewhere! Alternatives are included where possible in case there are stock or availability issues for the main parts.

There are a number of optional parts in the above list, depending on the build configuration you require. The following table shows the options outlined on the Motherboard v0.7 board:
| Part | V5 - Thru | V3.3 - Thru | V5 - No Thru | V3.3 - No Thru |
|---|---|---|---|---|
| S2 | Left | Right | Left | Right |
| JX | Close | Open | Close | Open |
| R11 | Yes | Yes | No | No |
| R12 | Yes | Yes | No | No |
| R13 | No | Yes | No | Yes |
| U8 | Yes | Yes | No | Yes |
NB: S1 is used to determine if the Arduino resets automatically when it is connected to the computer via USB. If you do not wish it to reset every time you connect it set this to closed.
