+GPIO 16  Relay 1 (Starlink)
+GPIO 17  Relay 2 (Fridge)
+
+GPIO 4   DS18B20 Bus
+
+GPIO 21  UART TX to Pico over CAT5
+GPIO 22  UART RX from Pico over CAT5
+
+RS-485/MAX3485 is fallback only and not currently planned.
+
+GPIO 34  Ignition Sense
+
+Future:
+- Additional Relays
+- Additional Sensor Inputs
