Is there some other step needed to get 3.2V? thank-you,en-USTelligent Community 13Thu, 06 Mar 2025 16:16:22 GMThttps://devzone.nordicsemi.com/thread/526232?ContentTypeID=1Thu, 06 Mar 2025 16:16:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d494ef14-8bb0-4c26-9665-42ededa1fdb0dejans<p>Hi,<br /><br />You can look at&nbsp;<a href="https://www.nordicsemi.com/Products/Development-hardware/Nordic-Thingy-91-X/Download?lang=en#infotabs">Thingy91X hardware files</a>.&nbsp;<br /><br /><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1741276869395v1.png" alt=" " /><br /><br /><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1741276976244v2.png" alt=" " /><br /><br />As you can see EXP_BRD_CTRL is coming from&nbsp;P0.03 on nrf9151.<br />TCK106AG datasheet contains the Figure where it is specified that control signal (coming P0.03 in your case) needs to be high for what you want to achieve.
