OK-1

OK-1 is a compact desktop controller: a 0.96" OLED on the front, a KY-040 rotary encoder/knob on the right, driven by an ESP32-S3-Zero stacked behind the OLED.

Experimental compact rev — same parts as v4, but the ESP32-S3-Zero is stacked BEHIND the OLED instead of beside it, which frees the lower 22 mm of the case.
