Hello, is there a way to connect Lora32U4 and send data to an Arduino Uno Board? Thank you.
Can you provide links the the boards or components you are refering to ?
In general though to send data from one LoRa device to another Arduino, you would need a LoRa device on the other Arduino.
For Lora32U4
and the classic Original Arduino Uno.
So you need a LoRa shield or similar for the UNO.
