A guy in our makerspace did buy one of this boards and i did get it running with this code LINK , you just have to set up the right pins

const lmic_pinmap lmic_pins = {
.nss = 10, // Digital pin connected to SS
.rxtx = LMIC_UNUSED_PIN, // we do not use these
.rst = 9, // Digital pin connected to RST
.dio = {2, 6, 7}, // Digital pin connected to 00,01,02 
};

You can find a wiki page here LINK and the board schematic here LINK

The board is fine but think it is a very expensive solution ..
