Shared hardware playbook for recurring parts: pinouts, wiring, snippets, and troubleshooting notes.
- boards/ : MCU board pinouts and quirks
- sensors/ : device wiring + code snippets
- displays/ : screen wiring and init snippets
- leds/ : NeoPixel and status LED patterns
- power/ : voltage/current notes, level shifting
- patterns/ : reusable sketches (I2C scan, encoder/button debounce)
- troubleshooting/ : common issues and fixes
- bom/ : trusted part links
Keep notes concise and text-first. Add wiring tables, minimal code blocks, and links to datasheets. Reference these pages from project READMEs instead of duplicating details.
