Completed the review and schematic creation for Round Light Engine V1. I corrected the support circuitry, added and wired the Pico, MCP23017, OLED, six encoders, three trackball headers, pull-ups, decoupling, and bulk capacitance; validation now reports no open errors/warnings for the checks run.
Open items:
- Trackball header spare pins remain intentionally unconnected until the exact breakout pinout is confirmed.
- The available 1x08 header footprint is horizontal/angled; use a vertical footprint later if you need straight-up headers.
Project files created:
Project Specification — Round Light Engine V1
Design Review Notes — Initial Schematic Input
Firmware Starter — Round Light Engine V1
Board Bring-Up Plan — Round Light Engine V1
Suggested next steps:
- Define the board size/mechanical layout for the single-sided console.
- Place controls by user-facing ergonomics: OLED top, encoders in rows, trackballs grouped by Lift/Gamma/Gain.
- Run single-sided PCB placement and routing, allowing jumper/0Ω links where needed.
