NRF24L01+ Module Range

Working with a pair of NRF24L01+ modules, Arduino Nano's and USB battery packs, I slightly tweaked maniacbug's pingpair sketch to give me a little visual feedback, a green blink for successful packet trip and red blink for everything else. The ping module had the red/green LED's and the pong just had a bright, white LED that I could see as I carried the ping module away in my hand. Range results for line of sight were 250m for solid connection (no timeouts) and 325m for a flaky connection (hold it just right). It's not very scientific, but I've repeated it several times.

NRF24L01+ Module Header Mod

So the typical NRF24L01+ module looks something like this with a not-so-handy 2x4 pin configuration and obligatory jumpers.



Using two 90deg headers makes this a little more breadboard friendly. It's not brain surgery, but it eliminates pig tails and a wireless module flopping around. The one downside is the pinout is a little confusing.
