https://devzone.nordicsemi.com/f/nordic-q-a/3574/how-to-check-if-nrf24l01-is-burnedHello, I know that Vdd on nRF24L01 module should be on 3.3V power and probably will be burned if get 5V power.... If in any case that happen at some point of experimentation how that would reflect on module? Should I still be able setting and readingen-USTelligent Community 13Mon, 08 Sep 2014 12:37:14 GMThttps://devzone.nordicsemi.com/thread/12959?ContentTypeID=1Mon, 08 Sep 2014 12:37:14 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5f08e6b6-e354-4bff-a893-9ab5c3dfda3dH&#229;kon Alseth<p>If the module has been used out-of-spec (outside 1.9V - 3.6V), anything can happen. It&#39;s therefore hard to say what the behavior will be, but you can usually see this by looking at the current consumption of the device, especially in suspend modes. This is because there are protection diodes on the pins, and if the circuit has been fried, the chance is that one of the pins are damaged and drawing excessive current.</p> <p>The best way to eliminate hardware issues is to change the module with a working one to see if the behavior is similar.</p> <p>Cheers, Håkon</p><div style="clear:both;"></div>
