There are two jumpers to configure CS and IRQ RFM69 pins. JP1 is used to choose between pins 6 or 10 for the RFM69 CS line. This is necessary to use an ethernet module in the same SPI bus. JP2 is used to choose between pins 2 or 3 for the RFM69 IRQ line. Default for ATmega328P seems to be pin 2 but for ATmega32u4 is pin 3.
- Serial gateway using an Arduino UNO JP1 and JP2 should be both 2-3.
- Ethernet gateway using Arduino UNO with Ethernet shield stacked JP1 should be 1-2 and JP2 2-3.
- Ethernet gateway with DFRobot DFR0342 JP1 and JP2 should be both 1-2.
Compact POE powered MySensors ethernet gateway
I have been using the shield with DFRobot DFR0342 board with success. This is a very compact POE powered ethernet gateway setup. DFRobot DFR0342 board is basically an Arduino Leonardo board with built in W5500 ethernet module and POE powered.
