I could not find a spec for the maximum current. However, looking at the schematics it seems like the 5V Boost regulator, XC9130.</p> <p><a href="https://www.torexsemi.com/file/xc9131/XC9131.pdf">https://www.torexsemi.com/file/xc9131/XC9131.pdf</a> </p> <p>The regulator is rated 500mA, and most of it is available to you. Usually less than 10mA and rarely up to 30mA is consumed by nRF52840.</p> <p>There is also an option to supply the board externally.</p> <p>Best regards,</p> <p>Håkon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/273990?ContentTypeID=1Fri, 09 Oct 2020 10:09:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:31877fed-262c-445c-92a0-26300f84076ehelsing<p>Hi Prince,</p> <p>I am looking into this and will get back to you later today.</p> <p>Best regards,</p> <p>Håkon</p><div style="clear:both;"></div>
