In a classic example of everything takes longer than anticipated, after I got those 2 units soldered I didn't really have a plan for how I would test them. While the Phazerville firmware now has low-level drivers for the new hardware (most of it anyway) none of the rest of the code supports it yet. After a couple false starts, I ended up hacking many lines of test code into a copy of Phazerville to print (to the Arduino Serial Monitor) all the raw ADC and other inputs, MIDI inputs, and a few commands I could send by from the serial monitor to override all DAC outputs and send a test MIDI message. I'm not a musician with a modular synth setup, so I ended up soldering several little adaptors from patch cords to my multimeter, a monitor speaker, and other stuff. It's a good thing I put this work into testing, as both of the PCB sets I hand soldered has a few places I missed.
Today those 2 hand soldered units are shipping to DJ Phazer (Phazerville firmare) and EH2K (Squares and Circles firmware).
