LoRa Advice for pin voltages

Projects Networking, Protocols, and Devices
1

I'm working on a new project involving LoRa and Arduino to capture data and send to a remote station.
Transmitter is running on an Arduino UNO R4 Wifi.
The Receiver is running on an Arduino UNO.
I am using the SoftwareSerial and pins 10 and 11 on both Arduinos as the RX and TX pins.
The LoRa modules I use is the RYLR998.
I have read that the Arduio pins are 5V pins and the 988 needs 3 V on the RX and TX pins as well as VDD pins. If that's true, then what is the recommended solution to dropping the voltages. I may already have damaged the 998 since they have been connected and tested without any voltage compensation. I have not gotten them to work, so that may be the reason.
So, I'm open to suggestions. Thanks.

Try a Google search on;

'Arduino logic level conversion'

Lots of info out there.

Perfect, exactly what I needed to know. Many thanks!!

So one other question. Can I use a voltage divider? The signals not changing that often (I only plan on sending data every 30 min or so), but I am concerned about the frequency of the signal being attenuated by the bridge?
I have ordered a logic level converter (10 of them in fact) so this is just a curiosity questions.
Thanks again.
