RFM69HW vs RFM95 - Both at 915 MHz

[zachaol]

Hello,

I love the chart located here: https://lowpowerlab.com/blog/2013/06/20/rfm69-library/

However I wish it had been updated to include the new RFM95.

• Does the RFM95 support Encryption?
• The RFM69 allows 61 bytes of user data, how much does the RFM95?
• I currently have a Master/Slave setup via a wired network. I want to transition to wireless, but the slaves do need to respond. How many slaves can connect to a single master?

Thanks!!!

RFM95 and 96 use LORA, a very different technology. They are different chips and work differently. Its like gas engines vs diesel engines
See this page for more on LoRa.
I will continue to add more information there as it becomes available.
For now you should note that the LORA chips do not have hardware encryption, but the packet engine supports much longer packets. However because of the modulation approach it may not be feasible to transmit very long packets. Its a technology that facilitates very long range at the expense of lower bitrates and hence longer transmission times.
