Despite reading datasheet that seems common for these Lora modules, is someone able tell me what are the difference between those modules (except Frequency 315/422/868/915 of course) ?
I need to get some aat 433MHz and I don't know if I need RFM98 or RFM96, so any explanation would really help me.
LoRa radios are usually spread spectrum rather than FM/FSK. And LoRa, to get their long range, need low frequency (not 2.4GHz), very low bit (data) rates, small packets.
