 I think the idea is that you could run this thing to eight different systems over RS485?
+Serial data is sent over this interface at 19200 baud every ten seconds. The data looks like this:

   * Entirely hand-assembled
   * Small heatsinks mounted to the GNSS, MCU, and NIC - absolutely not needed
+  * PPS from the GNSS is not connected to the MCU anywhere as far as I can tell. NTP server performance will suffer accordingly.
   * OLED screen mounted perpendicular to the board via a female header sitting flat is very clever!
