https://devzone.nordicsemi.com/f/nordic-q-a/4157/nrf-board-6310-5vHello, i have just a short, easy question, but i couldn&#39;t find the answer in the datasheets. Normally the ports on the 6310 board can deliver ~3.3V. Is it possible to increase that to 5V? If not, is somewhere on the board a source for 5V?

I am a bit confused. I am using a Starter Kit with a nRFgo Motherboard, which is connected via usb. So the supply voltage should be 5V. And my question is, can i somehow get access to this 5V? Or is the only possibility to use the pins with an output lvl of ~3.3 V. Thanks for your time.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/14874?ContentTypeID=1Tue, 21 Oct 2014 10:46:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:07bfa025-86bc-4171-a107-6eb48197cab8Stefan Birnir Sverrisson<p>Hi</p> <p>The supply voltage for the nRF51 is 1.8V - 3.6V, so the GPIO pins will output that voltage. There is not output from the chip that has higher voltage than the supply voltage.</p> <p><strong>Update 22.10.2014</strong> Sorry, I think I have misunderstood your question a little bit. Yes you can get 5V out from the nRF6310 motherboard under the OFF/ON switch on the motherboard. Th leftmost pin has 5V when the board power is switched off. You can measure the pins to verify that. The middle pin also has 5V when the board power is switched on.</p><div style="clear:both;"></div>
