AfReceived an order of RV09 potentiometers, but the style I got is not the right one. After bending the legs, they can be soldered. It is not the right component, but this hack will have to do for now.

I found these two pots in an older Seeed Studio Arduino Starter Kit. At a minimum this lets us verify that the footprint is right.

And a picture of the Assembled Unit:

Here are the wishlist items for the next board:

1) The second row of pots needs to move a litte bit down.

2) The pots could be spaced wider horizontally.

3) Add a 4 pin header so pins 9 and 11 can be connected with a jumper to Audio out. This will allow different synth software to run on the same hardware.

4) Find a spot for the Audio Out header.

5) Relocate the power switch

6) Decide on a communication protocol. If SPI, reclaim one I/O pin to use as a push button in order to have 8 pots and 8 push buttons.

And here is a video of the hardware being tested:

Audio out is working. Next is to figure how to map the pots to the correct values expected by the Mozzi synth software.
