I've been really busy recently, and I doubt I'll have much time soon. Along with that, this project won't actually be very useful to me and there are several (simpler) ones which I am doing. Therefore, I'm 'pausing' this project: it's no longer actively under development but I might continue in the future.

I have made sure the Dropbox link to the KiCad files is up to date, so if anyone wants to use the project they are welcome to.

Sorry!
