Compute: ESP32-S3-WROOM-1 - program with Arduino Core
Output: 1.8in LCD Display (4-wire SPI interface) 128x160 resolution
Inputs: 3 Buttons (Start, Reset, Boot) + Knob (Rotary Encoder + Push Button)
Buttons have low-pass filter
Knob uses quadrature encoding
Power rail shorts can be subtle and difficult to debug
Verify software settings before reworking hardware
Consistent net naming is critical in schematic design
Validate component footprints and physical dimension
Careful soldering is important for PCB reliability
