RFM69 + ATSHA204A Shield for Arduino.
This is another shield to build a MySensors gateway with Arduino UNO form factor. It includes RFM69 radio module and ATSHA204A crypto signing chip.
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.
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.
