nice board here, thinking to use the zero (pi3 has an spi problem seen in here)

but to just test the RAK831, can’t you just wire up the SPI lines and common ground? I saw the radio needs plenty of power and gets warm, does the shield give you a barrel jack connector powers both the zero and the radio? I just want to use wall power and use the wifi to my lan.
few really nice cases for the rpi3
but not much for the zero?
great write up here on outdoor use:
