Arduino Nano issue

I have "clearly" seen the instructions.
My question though is: why should it be different from one Nano to the other one ?But I suppose I should stop asking questions and stick to the manual :)
More seriously, I am very keen to understand the underlying phenomenons. What is the added current surge needed by the NRF receiving and decoding data the voltage reg (AMS1117) could not cope with ..?

It's low, about 15mA. But that is not the problem, the problem is the noise generated by the voltage regulator that supplies the 3.3V.
You should buy your nanos from AliExpress, they are 1/3 of what you pay (I'm talking about the cheapest ones) and are exactly the same, just order in advance as the shipment is long. But on a "safety" point of view you won't lose compared to ebay even with sellers in your country, they have a buyer protection system too. -

But, considering the price, I will check twice. For the moment, what I see is huge shipping prices ;) -

@qqlapraline try this, looks like free shipping to France:

@qqlapraline interesting! I've never seen that high shipping costs, but it seems like France is crazy expensive.
@mfalkvidd Yep. It's the same for some other European countries (like Netherlands) but not for others..weird
@mfalkvidd For the other Nano using CH340, it really looks like the non-working ones I bought on Ebay.
But thanks anyway.

@mfalkvidd, nice pickup ! Thanks !
