Using a NRF24L01+ and RS232 Module together

Hi,

I am working on a project which requires me to wireless interface with another Arduino and a serial connection (RS232) to a robot. I was wondering if there will be any issues? I am considering getting the following.

Radio Module

Serial Connection

Thanks!

Yes, those should work.

Be sure to power the radio modules with 3.3 volts, not 5. And they will need much more power than the Arduino 3.3 volt pin can supply.

Using a Leonard or Mirco would allow you to use hardware serial without clashing with the upload/debug.
Or pick any other microcontroller with more than one hardware serial like the Due/ESP32/teensy/...

This Simple nRF24L01+ Tutorial may be of interest.

Wireless problems can be very difficult to debug so get the wireless part working on its own before you start adding any other features.

The examples are as simple as I could make them and they have worked for other Forum members. If you get stuck it will be easier to help with code that I am familiar with. Start by getting the first example to work

And maybe also Serial Input Basics - simple reliable ways to receive data.
