CV Generator
A 3x CV Generator for synthesizers. Outputs are -10 to +10V DC with about 20mA source/sink current. 8HP Euro form factor. Also a buffered one-shot 5V CV with a manual pushbutton for triggering events.
The project uses an ATTINY 1624 MCU with the cool AnalogReadEnh() function to drive the OLED and do the AD conversion.

If you build this module you will need 2 PCB's, the main board and a front panel. The front panel gerber is included below as a zip file. I suggest you indicate to PCBWAY that you want to pay the extra $1.50 to not have the project # silked onto the front panel. I'd recommend black soldermask with white silks.
