This is board re-resign of the existing thru-hole design, with a new surface mount version using a smaller ESP32-S3 controller while adding an optional MIC input circuit. Obviously, it is a work in progress, and I'm currently trying to get the Sketch code to compile with the new S3 and the later Library releases for FastLED and Si5351. I will update the page once the Libraries are stable and working so I can order some boards. Currently using breadboard protos to get the final IO pin assignment.
