NRF24L01 gets hot while using external bettry

hey i am just a beginner and i am trying to make a transmitter for my quadcopter but am having issues with nrf it gets really hot when i give 12v to it. what will be am doing wrong..!!

here is my schematics…

The issue could be due to the nrf24L01’s supply voltage requirements — which is recommended to be maybe 3 to 3.6 Volt. You might be supplying it at about 3 to 4 times the recommended level. I’m only reading what you wrote. You said ‘when I give 12V to it’. So if that’s what you wrote, that’s what I will assume.

The ground terminal on your regulator is not connected to 12V -, you're probably putting 12V on the radio and may have killed it. :(

12V almost certainly destroyed that chip instantly. It certainly shouldn't get hot if its working, slightly warm at most.

im not giving 12V to nrf giving 3.3V to nrf24 from my regulator lm1117 . but still same issue need more help...

need more help...

Need more information. Please post detailed photographs showing all components and wiring.

Okay, now we know how it [u]should[/u] be wired - but I made a specific request: "Please post detailed photographs showing all components and wiring" because we need to know how it is [u]actually[/u] wired.

If you choose to ignore the request, all we can assume is you wired something wrong and damaged the NR24L01.

This is what made me think you had miswired the regulator, the dotted line looks like an after thought.

Hi, Do you have a DMM to confirm 3.3V to the nrf?

Thanks.. Tom.. :)

edgemoron: This is what made me think you had miswired the regulator, the dotted line looks like an after thought.

I agree. Also, the capacitor has these questionable terminals drawn on it, that are connected to nothing, while two lines come in and magically connect to the capacitor --- on the body somewhere.

And if it is an electrolytic cap, then hopefully the polarity is ok.

Also you have no capacitor on the input side of that regulator so it could be oscillating. But if the transmitter is getting hot then it looks like it has been damaged.

OP, You have an interesting name. Doesn't Mujahid mean "One engaged in a jihad, especially as a guerrilla warrior?" Who are you striving against? Is it just a name like "warrior" in english?

Is your "quadcopter" part of your jihad?

Interesting in any case. If it's getting too hot, I'd second the idea that you may be supplying too much voltage to the module. Can you measure the output of the lm1117?
