Have you calculated the capacitance you&#39;ll need for C8 and C9?<br /><br /><br /></p><div style="clear:both;"></div>RE: nrf52832‘s unstable current causes it can't be connectedhttps://devzone.nordicsemi.com/thread/164964?ContentTypeID=1Thu, 10 Jan 2019 14:32:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f624341d-7c2f-4888-97e7-19c4ddfa11e3XinKai<p>The CLK configuration is fowlling</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/pastedimage1547130627793v1.png" alt=" " /></p><div style="clear:both;"></div>
