RFXmngr version 26.0.0.1    24-01-2026

• Orcon fan corrected

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.

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