I accidentally swapped the wires for VCC and GND that I was holding when plugging in to a plugged arduino uno. I wired everything else correctly. I heard the short circuit thing that windows does to prevent the port from being damaged. The module only returns "���" as a response when running the "GettingStarted" sketch from Rh20. If it is indeed dead, can I use a diode to prevent this from happening again?
Does this mean you can still upload code to the Arduino?
On the serial monitor, you mean?
Yes, and yes. The Arduino works fine, I think I broke the nRF24L01 though?
That's possible.
That doesn't explain the "���", however. Did you set the baudrate on the serial monitor to 115200 when running the TMRh20 NRF24 GettingStarted sketch?
Ohh. It worked on my other nRF24L01 without changing anything so I hadn't considered that. Thanks, I will check it tomorrow.
P.S.
the one I think I broke was the version with PA & LNA if that changes anything.
Thanks dor adding that, but no, doesn't make much of a difference; it's still a matter of just checking and hoping it still works. There's a decent chance it survived, but you'll have to verify.
I would not trust it for anything important even if it works. Integrated circuits can be damaged but it can take nanoseconds to be destroyed or many months until it fails. I always assume it will fail.

Never trust a compnent that has been stressed anyehere near its maximium limit. Toss it in the trash or put it in that Hotel California box.

Cool!
While I'm sympathetic to the cautious remarks offered above, I have to admit that I generally just keep using hardware that has gone through such 'traumatic' events, at least in my own personal use. So far, so good; it hasn't gotten me into any troubles yet.
