1U Blank/Mono to stereo converter/Cheat sheet

A simple 1U blank panel at the surface, with common Eurorack circuit cheat codes written on the front (resistor e-series, op-amp inverting and non-inverting formulae, a mm ruler on one side, an HP ruler on the other, and op-amp pinouts for 8 and 14 pin packages).

Two mono and one stereo Thonkiconn jacks can be optionally soldered to use the module as a mono to stereo output stage (nice and easy way to connect headphones if you have no stereo output module!).

Given away in a limited run at Synthfest 2022.
