LAN module for RFX-433EMC and RFX-868

Filed under: Using — RFXCOM @ 1:56 pm

The W5500 LAN module can be used on the RFX-433EMC or RFX-868 using the RFXCOM protocol or MQTT.

The option is connected to the RFX with a Push-To-Fit connector and can be soldered for a more reliable connection.

  • Open the enclosure.
  • Insert the Push-To-Fit pins on the component side in the PCB. Check that the 2 pins are inserted at 3V3 and GND
  • Insert the PCB in the top of the enclosure.
  • Hold the bottom part on it and mark the points where the connection PCB is.
  • Make a 3.5mm deep recess in the bottom part so that the enclosure can be closed.
  • Flash the LAN software.

See also chapter 10 in the RFX User Guide.

Or connect a W5500 module with the RFX PCB with 8  short wires with a length < 10cm.
See chapter 10.2
