Any idea what this is? There is no printing on the back.

I think you attached the wrong image.

Indeed I did, thanks. Must be a Tapatalk bug, because I used the "take photo" option, not the "upload from camera roll" option.

Based on the component numbers, it looks like a daughter board for something else. Any chance it could be an LFO?

It's a jFet tester for measuring vgs. Looks like the one that came with the first version of the NomNom.

Ah ha, yep. That's what it is and where it came from. As it happens, I've got a use for this right away—convenient! Thanks.

I did this with my first PCBs... then I got sick of trying to figure out what bloody revision or even project the damn boards were

I think I ordered a NomNom just to get that tester board.
