Arduino wireless communication with nRF24L01+

I’ve been experimenting with the nRF24L01+ modules recently for wireless communication between Arduino boards. For a simple setup, two Arduino boards can communicate using the nRF24L01+ over the 2.4 GHz band. I tested a basic two-way communication setup where one Arduino sends a message and the other responds.

One thing I found important is the power supply. The bare nRF24L01+ needs 3.3 V, and the module can be a little sensitive to power stability, especially with the PA/LNA versions.

I’ve put together the wiring and the complete setup here in case it’s useful to anyone working with these modules:

For those who have used nRF24L01+ before, what kind of range and reliability have you been getting in real-world indoor setups? I’d be interested to hear what worked well for you.
