https://devzone.nordicsemi.com/f/nordic-q-a/43511/input-current-on-nrf52-dkHello to everyone. I want to know, how many current can the board of nRF52 DK work with? . My PC have one USB 3.0 input, that provides 900 mA when I connect the board, and one USB 2.0 that provides 500 mA when I connect it. O those cases, when I connecten-USTelligent Community 13Mon, 11 Feb 2019 23:02:46 GMThttps://devzone.nordicsemi.com/thread/170470?ContentTypeID=1Mon, 11 Feb 2019 23:02:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b9024011-fda8-4ada-b5eb-5c9871684df5JK0201<p><br />Thank you so much!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/170405?ContentTypeID=1Mon, 11 Feb 2019 14:29:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ddcbff24-06e5-4698-8840-b6d159f36069Andreas<p>Hi,</p> <p>&nbsp;</p> <p>As Turbo kindly advised, the fact that it is rated 1000mA is not a problem.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/170229?ContentTypeID=1Sun, 10 Feb 2019 04:33:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3c8dbc70-320f-4c33-b2a0-e8f41f308266JK0201<p>Thank you, Turbo J.</p> <p>So, there&#39;s no problem if I use 1000 mA to feed the board, right?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/170210?ContentTypeID=1Sat, 09 Feb 2019 09:15:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d259355e-92f9-4e5c-a313-79ef553b77afTurbo J<p>Those USB PSUs are (usually) voltage sources an should be safe to use - unless you bough cheap chinese (or similar) stuff, which has not enough mains isolation. These can kill you in fault cases.</p> <p></p> <p>The blinking LED only signals that there is no USB host present. USB chargers do not use USB data protocols.</p><div style="clear:both;"></div>
