So same thing happens, the noise gets injected. But you also need to check the theory of super-Chris, overloading the supply. Did you check the 3.3V rail when the NRF24L01 is in place? | |

Moreover, the NRF24L01 board I'm using draws 71mA. I'm going to try running it off of the 5V line with a 3.3V LM317 regulator and see if that fixes my problem. | |
