It's not unthinkable that a strong enough ESD pulse will fry the chip. It's good to hear you found a solution 🙂

Today i saw as a discharge in power line killed nRF24 right through the LDO, but LDO and ATmega is fine although. It seems that this is just an ESD problem. nRF24 is more susceptible to ESD damage than everything else in design. Also, if anyone will encounter same problem, it looks that grounding a soldering iron and using an antistatic wrist strap solved all problems.

Yes, of course.

Here is the link to the old topic: https://devzone.nordicsemi.com/f/nordic-q-a/560/nrf24l01-problem-in-power-down-mode

Link to the modules: https://www.ebay.com/itm/20pcs-2-4GHz-NRF24l01-Wireless-Module-Mini-Power-Enhanced-SMD-Version/253048458498?hash=item3aeadd0d02:g:GeIAAOSwf~9Zadf4

Thats not a place where i bought them. I bought them from different sources (local shops in multiple cities, ebay), but they look and cost almost the same as showed above. I thought of possible counterfeit, but i found no difference between modules i bought.

Yesterday i finished some devices, checked them, and they were working fine. Today my colleague came and tested a device, he found that it started to consume high power. Only thing that he did is he changed a battery. I think that there may be a problem with flux or ESD, but i have no actual clues

Do you have a link to the module you use, and the old cases you found that discuss this issue?

Best regards
