A self-expanding ESP32 PWM board

I’ve been working on a little ESP32 expansion board/shield for an LED project I’ve been working on. One of the nice things about the ESP32 is that it has a peripheral known as “LED control” that provides 16 independent channels of PWM for controlling LED brightness, and my project uses that capability.
One of my projects is going to require all 16 channels, so I wanted to do a board that would support 16 channels, but I also wanted a version of the board that would only support 8 channels.

Project info at Eric’s Arcana and RiderX site. It’s also up on Tindie.
