Which LoRa radio with SparkPNT FPL?

GPS/GNSS SparkPNT / Consumer Products

I just ordered SparkPNT FPL. I’m not sure which kind of LoRa radio do I need for setting up RTCM between my RTK base station and the FPL. The base station is Raspberry Pi 5 with Flex pHAT.

Could I use SparkFun Pro RF with an antenna? Should I connect it to RPi or pHAT?

Hi @Samufun ,

Just in case it is not clear from the docs:

The Facet FPL has a built-in LoRa radio. But it is only compatible with other Facet FP units and the original Torch (if you upgrade the Torch LoRa firmware to 3.0.0). It is not compatible with the Pro RF LoRa, or the LoRa Serial Kit.

But, you can disable the built-in LoRa, and instead: connect a separate external LoRa unit to the Facet FP, and a matching one to your pHAT assembly.

I hope this helps - please let us know if you need more information,
Paul
