<p dir="auto">As mentioned in topic, I want to know if the 3.3v version will give enough and stable power for the nrf ?<br />
Also what is the totoal maximum power consumption which the mini can support if I want also to power up transistors or TRIACs ?</p>
<p dir="auto">Thank you.</p>

As far as I remember these can use much more power.</p>

<p dir="auto">The <a href="https://www.arduino.cc/en/uploads/Main/Arduino-Pro-Mini-schematic.pdf" rel="nofollow ugc">official pro-mini</a> uses an <a href="http://www.micrel.com/_PDF/mic5205.pdf" rel="nofollow ugc">MIC5205</a> voltage regulator that can deliver maximum of  150mA.</p>
<p dir="auto">Most clones uses a cheaper regulator (such as the 100mA <a href="http://www.ti.com/lit/ds/symlink/lp2981a-30.pdf" rel="nofollow ugc">LP2981</a> that I found in my pro-minis).</p>
<p dir="auto">The official nRF24l01 radio consumes about 15mA while transmitting/receiving.  You have to add on top of it the arduino itself, as well as any other components that you are powering up.</p>
<p dir="auto">And to be on safe side I would not use more than 60-70% of nominal regulator's output.</p>
<p dir="auto">Hope it helps...</p>
