Lilygo® ttgo lora32 WITH ARDUINO UNO LORA nfr24l01

Hello everyone, I am trying to communicate an arduino uno that has a lora antenna, which is nfr24l01, with a lilygo® ttgo lora32 that has a frequency of 915mhz, could someone help me connect these two devices, since I have found in internet how to connect two arduinos or two esp32, I have also downloaded the necessary libraries for the esp32.
thanks everyone

Hi,

I think you will find the NRF is a 2.4GHz WiFI module and not a Lora module.

oh I understand, haha I'm inexperienced, and what lora module do you recommend to connect to the arduino?, since I have the esp32 with lora but that is included

Another ESP with Lora, would be best.

A UNO is a poor choice for connecting a LoRa module. LoRa device are like most all recent electronics 3.3V logic. The UNO is from a previous time and uses 5V logic.

So to use the LoRa module on a UNO you need to use logic level conversion circuits or buy one of the specific shields designed for a UNO.

A 3.3V Arduino Pro Mini would be a far better choice for the processor or just another ESP so the code would be the same.

Otherwise all SX127X type LoRa modules use the same Semtech device so there is little to choose between them. Avoid however the UART based LoRa modules, you want the SPI based ones. Some LoRa modules have a u.fl connector on them which can make connecting an antenna easier.
