It appears there are three identically priced models available: RFM96 (433MHz), RFM95 (868MHz), RFM95 (915MHz) and the slightly cheaper RFM98 (433MHz).
There are allegedly also extended range and power modules available with the 'PW' suffix, offering low receive sensitivity(–136dBm) coupled with Enhanced +30dBm output power, but these do not appear to be in wide retail distribution so I didn't find a pricing source.
They also claim to offer sub-GHz transceivers in similar module form factors but again no visible distribution so perhaps not yet available.
Meshtastic hardware list @ https://meshtastic.org/docs/hardware https://meshtastic.org/docs/hardware appears to be mostly LilyGo-branded modules which are based on Semtech ICs https://www.semtech.com/products/wireless-rf/lora-core/ https://www.semtech.com/products/wireless-rf/lora-core/
Most promising embedded lib @ https://github.com/jgromes/RadioLib https://github.com/jgromes/RadioLib which supports both manufacturers' IC families across numerous architectures.
- KennyBlanken 4y agoFYI the different frequency bands are for different regulatory markets, and one should figure out which module is legal in their country before buying. Before buying a module, I would recommend watching Andreas Spiess's youtube videos on LoRa; he has several.
- contingencies 4y agoThe sub-GHz hardware is non-LoRa ISM-spectrum. However, again this has differences in specific subspectrum licensing. While learning about radio regulation is perhaps interesting to some people and arguably important, practically speaking this stuff is not high power so it would be hard to cause problems with it.
