This is the LoRa 9x @ 900 MHz radio version, which can be used for either 868MHz or 915MHz transmission/reception - the exact radio frequency is determined when you load the software since it can be tuned around dynamically. They can easily go 2 Km line of sight using simple wire antennas, or up to 20Km with directional antennas and settings tweaks.
To use the LoRa Featherwing with a Pybadge/Gobadge, you need to connect some pads on the board itself. Solder some jumper wires as follows:
RST -> A CS -> B DIO1 -> C IRQ -> D
You also need to connect an antenna. The easiest is to cut a small piece of wire to the correct length based on the desired frequency:
EU868 Mhz - 34.54 cm
You can also use a fancier solution such as a uFL SMA connector with matching antenna.
