However, the pin has to be set to high-drive mode. In high-drive mode, Nordic chips allow 3-5 mA per pin. Also, ensure that you stay within the total current limit and per-pin IOH/IOL limits. The sum of the GPIO currents shouldn&#39;t be higher than the recommended total GPIO current for the device.</p> <p></p> <p>Best Regards,</p> <p>Samruddhi</p><div style="clear:both;"></div>
