I was lucky enough to receive the first revision of the Dragino LoRa board: it simply works.
As it is basically an RFM95 breakout it should work together with the ESP, you might want to consider the V1.2 board as that is more flexible w.r.t. the breakouts. It was revised based on inputs from people on this forum to make it more flexible see the dragino wiki for the difference in appearance.
For ESP8266 LMIC stack see messages above.
