https://devzone.nordicsemi.com/f/nordic-q-a/386/analog-input-pins-on-motherboardHello! I have a very simple setup with Arduino board (see attachment) I wish to move to the nRF51822. I have the development kit and the nRF Go motherboard. As I understood from the docs I should connect to P5 connector which is not mounted onen-USTelligent Community 13Fri, 30 Aug 2013 08:46:37 GMThttps://devzone.nordicsemi.com/thread/2028?ContentTypeID=1Fri, 30 Aug 2013 08:46:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f90391a4-07cf-4d8e-92ad-abc74de59ef8Ole Morten<p>You can take a look at the <a href="https://www.nordicsemi.com/eng/content/download/13247/213200/file/nRF51822%20Development%20Kit%20-%20Hardware%20files%202_0.zip">hardware files</a> for the Development Kit module to see how P5 is connected to the chip, and the Product specification lists the pin functions in table 1.</p> <p>Basically, you can connect your A0 to for example AIN7, which is P0.06 on the chip. Remember to comply with the maximum ADC input voltages, as given <a href="https://devzone.nordicsemi.com/index.php/what-is-the-maximum-input-voltage-for-the-adc">here</a>.</p><div style="clear:both;"></div>
