https://devzone.nordicsemi.com/f/nordic-q-a/33448/led-powerI have a custom board, that basically consists of a nrf52832 module (ebyte), a button and a LED. The LED is connected as in pca10040: VDD-&gt;220R-&gt;LED-&gt; ground to p17. I assume (!) that LED power consumption should be [VDD-Voltage drop]/Resistance= (2en-USTelligent Community 13Wed, 18 Apr 2018 09:25:34 GMThttps://devzone.nordicsemi.com/thread/128758?ContentTypeID=1Wed, 18 Apr 2018 09:25:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:90098597-c739-43d7-9e77-2cad9c0cac3cketiljo<p>If you have the drive strength set to standard, then the led current will be only 0.5 mA. Set it to hi-drive of you need more. You can leave it like this, no problem. But the light output may be low.</p><div style="clear:both;"></div>
