Excpet&nbsp;if&nbsp;you are powering the board using using VDDH (2.5V - 5.5V), then the GPIO voltage can be set in UICR:&nbsp;<br /><a href="https://infocenter.nordicsemi.com/topic/ps_nrf52833/uicr.html#register.REGOUT0">https://infocenter.nordicsemi.com/topic/ps_nrf52833/uicr.html#register.REGOUT0</a>&nbsp;<br /><a href="https://infocenter.nordicsemi.com/topic/ps_nrf52833/recommended_op_conditions.html">https://infocenter.nordicsemi.com/topic/ps_nrf52833/recommended_op_conditions.html</a>&nbsp;</p> <p>Kenneth</p> <p></p><div style="clear:both;"></div>
