343 +Each LA66 module includes a (% style="color:blue" %)**world-unique OTAA key**(%%) for LoRaWAN registration.
286 286  
287 -Put a jumper cap on JP6 of LA66 LoRaWAN Shield. ( the jumper is to power on LA66 module)
345 +Besides the support of the LoRaWAN protocol, LA66 also supports (% style="color:blue" %)**open-source peer-to-peer LoRa Protocol**(%%) for the none-LoRaWAN application.
288 288  
289 -Connect USB TTL Adapter to PC after connecting the wires
347 +LA66 is equipped with (% style="color:blue" %)**TCXO crystal**(%%) which ensures the module can achieve stable performance in extreme temperatures.
