Starting with this version, there are no more SMD chips. It has been replaced with the “Black Pill 2.0” board and a single 1k resistor. The other change was the addition of the choice of another amp. The NS4110b amp has slightly lower noise than the PAM8610.

In my kits, look for a single resistor, and I mark on one of the strips that it is 1K. That is the resistor that goes between the black pill board and the resistor networks.

V3.7

There were only a few minor changes that I made in 3.7. I added a second WPC95 header to get rid of the weird cable requirement, and then added a spot to rotate the OLED display for in DE machines. The other thing I added (and what I consider more important) are notation in the silk screen to aid in assembly. There are white boxes over the power header sections where the pin should be removed, there are little boxes to denote where the cable header notch should go, and for the PCM5102 I added a few to mark which pins needed to be connected. See the picture below.
