yeah, I don’t think you want latching, as the relay switching is handled by the PIC…..I tink.

 

[Diynot]

EA2-5SNJ is latching, EA2-5NU is non-latching. The S denotes Single-Coil Latching.

Welp, that’s def a meaningful difference.

 

[Feral Feline]

EA2-5SNJ is latching, EA2-5NU is non-latching. The S denotes Single-Coil Latching.

So I want the EA2-5SNJ for my Strat and the EA2-5NU for my ... I just realised I don't have a humbucker guitar... even my SG is single coils.

So EA2-5SNJ it is then, and, OH! Can I still play fingerstyle or do I HAVE to use a PIC?

Oh, wait... My BC Rich Bich has humbuckers.

Never mind.

I've gone over the PCB and created a BoM for this PCB.

I'll fix the errors or omissions if you find any, please feel free to check because I'm a guitar/bass player, not an electrical engineer, and I have a very limited understanding of how any of this actually works.

Just one more thing... 16V is OK for the E-caps on this thing, right? I looked over the schematic and couldn't see anything that looked like it might be a problem, but my talents lie in other areas so I could be missing something important here.

So long as you’re not trying to run it at anything higher than 9v it should be fine. The regulators are only pushing 5v

That's what I thought. I don't usually try running anything over 9V.

I think best practice is to use 25v (roughly double the potential voltage seen), but pretty sure 16v will be fine

I usually do that but I grabbed a bunch of 16Vs so I need to use 'em up.
