# Project Decisions
|
|
|
|
## Communications
|
|
|
|
Primary:
|
|
- UART over CAT5 initially
|
|
|
|
Backup/Future:
|
|
- RS-485 over CAT5 if UART proves unreliable
|
|
- WiFi HTTP API
|
|
|
|
## Dashboard
|
|
|
|
- Touchscreen only
|
|
- No physical buttons required
|
|
- Screen sleeps when ignition is off
|
|
- Touch wakes display
|
|
|
|
## Relay Design
|
|
|
|
- ESP32 relay board does NOT switch loads directly
|
|
- Bosch-style automotive relays switch all major loads
|
|
|
|

|
|
- Starlink
|
|
