Adafruit (PID 3072 RFM95W LoRa Radio Transceiver Breakout - 868 or 915 MHz

I've been having a lot of fun with these. Some of them I soldered a uf.l connector, while others I soldered a SMA PCB-edge connector. Both work well. The nice thing about this particular break out board is that it has a level shifter, so can work with 3.3 VDC devices or 5 VDC devices, and it has its own voltage regulator, so you don't have to worry that while transmitting it may burden the arduino or ESP8266 or ESP32 you may be using. If I had to give it any negative comment, it would be that there is no way to bypass the regulator, so I can use these with a common high power 3.3 VDC DC-DC module, to avoid the additional loss from the built in LDO regulator. Using a 8 dB gain antenna, I was able to reach well over 10 miles in my test using a spreading factor of 7, and nearly 30 with SF12.

worked as expected.

Good power output and easy connection. The antenna options are a great design attribute

Got it to work

I like the range of the LoRa products. This is working well for distant IOT sensor hub transmitting through concrete and steel walls to a my LoRa to Wi-Fi (MQTT) bridge.

Why limit a project to only use WiFi, when you can simply add these and extend your range by a lot! Okay, I'm sure there are still some reasons. The commands are very straight-forward, and these modules are very robust. I haven't had any problems.

All in the title, I cannot seem to get these to work. I have gotten 5 total, I have tested them across 3 different arduino nanos as well as an arduino uno, I have followed a several tutorials on how to use them, I've tried every different configuration I can think of, ive tried dozens of different sketches, I've read the documentation extensively, I've tried using external power sources, I've tried setting different frequencies, and all of it yields the same result that they simple fail to initialize. I'm praying that I'm missing something dumb and simple, because these devices promise the world, but I've checked my code and my pin connections a hundred times and I cannot seem to get them to initialize at all. If anyone has any suggestions, or there are any common gotcha's that are missing from other comments or the documentation then I'm all ears

Hello, I’ve used other radios before and they were awesome. This time I bought this to use them at 915 MHz, but I a m bit concerned since, as shown in the picture I am attaching, it says they are RF95W, but in the chip itself it is engraved RF96, I went to adafruit’s page and it seems that the RF96 is for 433 MHz. Could you help on clarifying if they are item 915 or 433 MHz devices?

the product was sold as "New" but the contacts were in very bad shape, they loocked as they were de-soldering at least two times. not recommended.

Acheté pour monter une gateway one channel, il ne lui manque qu'un truc : une embase pour connecteur d'antenne . Pour le reste elle fonctionne très bien. Monté pour ma part avec un ESP32 et testé en mode node ou gateway

Werkt uitstekend. Aangesloten op 3.3v en 5v Arduino's met slechts een draadje als antenne. Heeft desondanks daarmee toch een bereik van makkelijk 2 km. Werkt goed met library van Radiohead, gebruikt binnen de Arduino IDE. Werkt ook goed op Sparkfun Samd21 (mini). Aan te bevelen!
