The first step to creating my own BoM for this project, was to convert the Mouser BoM. I found it very confusing that all the components were mixed up and that they didn’t have identifiers for where they were on the board. I thought that someone must have documented building one of these things, or made a video, or something. Either my google fu is weak, or pretty much nobody has bothered.
I think there was some confusion, not helped by the amazingsynth.com website, about what this thing is actually called. Is it a Module Tester, or a Noodle Toaster…? You’d think if it was Noodle Toaster, the big page title on your website might read New Noodle Toaster v2 PCB and pre-flashed chip set. 
Anyway, searching for Noodle Toaster, rather than Module Tester, eventually turned up a couple of recorded livestreams of someone trying to build it. I wouldn’t say it made for riveting viewing, but it was reassuring watching someone who appears to have way more knowledge and skill than me, struggle to figure out what was going on.
It further highlighted the fact that the Mouser BoM is a load of bollocks and should be avoided at all costs contained a load of inaccurate components. The other thing it highlighted, was that I could probably get an accurate list of components from the original schema files that are on GitHub. They wont load in KiCad though, but thankfully @analogoutput has cloned the original repo and converted the files to they can be loaded by KiCad.
Armed with a freshly exported bill of materials, it was simply a case of going back through each component and trying to ensure I had the correct amount of the correct thing. I’m not 100% sure I’ve got everything correct, so do your own research and take the following table with a pinch of salt:
