How to register SparkFun LoRa Thing Plus - expLoRaBLE on The Things Network

I recently bought a SparkFun LoRa Thing Plus - expLoRaBLE and am following the hookup guide. However, it seems like the guide is outdated especially when it comes to device registration. I tried to manually register the expLoRaBLE but the only specifications I can find is for the frequency plan. What LoRaWan Version and Regional Parameters Version should I specify?
