Works, but has significant problems.
- Fabricator: JLCPCB
- Material: FR4 (Tg 135)
- Layers: 2
- PCB thickness: 1.2mm
- Solder mask color: black
- Silkscreen: white
- Surface finish: HASL (with lead)
- Copper weight: 1 oz
- Via covering: tented
- Board outline tolerance: +-0.2mm
- Appearance quality: IPC Class 2 Standard
- Silkscreen technology: Ink-jet/screen printing
- touch button on GPIO0/BOOT doesn't work properly, leaving the circle shape unused
- no pull-up resistor on ESP32 pin EN
- rotary encoder function icons don't match the actual modes
- wire holes diameter is too narrow
- touch buttons work better without resistors
- WS281x signal overshoots and rings on long wire with the specified resistor value range
- the power LED is too bright with the specified 330 ohm resistor
- circle shape appears a bit larger than the others
- release version is not visually accessible on the bottom layer once mounted
