Wifi + LoRa telemetry add-on

PX4 Autopilot
4

I spent the day putting together a PCB. 36mm x 36mm to fit on top of a pixracer with a connector to fit into the pixracer’s esp-01 socket. The board contains:

  • esp8266 using either an esp-12 or a esp-07 module (built-in vs ext antenna), in both cases the esp module sticks over the edge
  • HopeRF rfm96/rfm98 LoRa module with board-edge SMA connector
  • two RGB LEDs to indicate Wifi and LoRa status / activity
  • cut-out to allow vertical PWM connectors on the pixracer and to allow dense stacking
  • switching regulator with jumper to select between using the pixracer’s LDO or the switching reg (needs 5v input)
  • FTDI connector for initial flashing and debug output gpio2/tx2 connector

Now wait 2 weeks to get PCBs back… The mavesp firmware should work with just some minor tweaks to adjust pins and then the fun of jamming some LoRa code in will begin. Assuming the PCBs work, of course…
