Lora ISM bands #1

Hi Jaimy,

I am going to order two JL-601 cards on Tindie Tindie chat is not working for me, then I wrote here the message.

Sometimes I need precision logging. I have Agilent 34970 for Lab, but your precision Low Power Logger can help on the field. It looks a nice solution! I have studied the RFM95CW module datasheet, and it looks to work on the EU ISM band. I just wrote you not to oversee something, please confirm, that I can use it in the 868MHz LoraWAN band and libraries you used.

Thanks, Csaba Toth

Hi Csaba, I'm sorry but for some reason I am only just seeing your comment now. You can use the RFM95CW at 868Mhz, but there may be a small impact on signal strength/range as the matching network is tuned to ~915. The RFM96 would give the best performance. It is the same radio IC, but the RF passives are tuned to ~868Mhz. The libraries I have tested all allow you to set the frequency to the appropriate band.
