The PCB design is finished, and I received the (almost) entirely populated first prototypes from https://jlcpcb.com/ (they didn't have the SSI2144).
Here's a picture of the PCB:
I am now working on porting my firmware on this new version.
By the way, here's what has changed since my earlier post:
- One more envelope, dedicated to oscillators (the filter envelope was used beforehand, but it felt a bit cheap...).
- Instead of a SDCard slot, I now use a soldered flash chip, which will be accessable through USB.
- Shipped with a machined enclosure, the potentiometers, the display, the 16 keys keypad, the knobs, and probably a vinyl for the panel, assemble it yourself (about 250€), or entirely assembled (about 300€).
