The dashboard enclosure will include an M9N GPS module connected to the ESP32-S3 dashboard over UART. It will provide GPS fix status, satellite count, position, speed, and UTC time. Future work will use GPS time/location for automatic timezone and DST handling.
## XIAO sensor-node RS485 link
The dashboard uses the Waveshare ESP32-S3-Touch-LCD-5B onboard RS485 receiver for the XIAO BNO086/MAX-M10S node:
| Function | Dashboard GPIO |
| --- | --- |
| RS485 RX | GPIO43 |
| RS485 TX | GPIO44 |
The onboard transceiver handles direction automatically. Configure 115200 baud, 8-N-1, connect A-to-A, B-to-B, and share ground. Keep **USB CDC On Boot** enabled so USB diagnostics do not claim the RS485 UART pins.
