Choosing LoRA Board

Wireless & IoT LoRa (Long Range)
1

I need to do simple point to point wireless serial data transmitting over long range (a couple of miles outdoors). IP not needed.

Would either the LoRa Gateway - 1-Channel (ESP32) or the Pro RF - LoRa, 915MHz (SAMD21) work for my application? Which one would be the better choice?

Thank you!

The biggest difference in your case would be the LoS range of each product. The ESP32 can do 1KM(0.62 miles) versus the RFM95W which can do 2KM(1.24 miles) with the SAMD21 board.

You may want to lean towards Pro RF - LoRa product if looking for over 1 mile of distance.

Hope this helps.
