https://devzone.nordicsemi.com/f/nordic-q-a/117019/use-nrf52840-as-nrf52833I am developing a product that uses Gazell and USB. During development, I am using the nRF52840 due to availability. For mass production, I will use the nRF52833 to reduce costs.

Was the project built for the nRF52840 or the nRF52833, and what exactly did you try to do that didn&#39;t work? How did it fail, was any error code returned?</p> [quote user=""]1. What problems are anticipated that may arise from using an image built as nRF52833?<br />[/quote] <p>The nRF52833 and nRF52840 is very similar but have different level of support for some peripherals. It&#39;s not safe to build a project for nRF52833 and then run it on the nRF52840, there might be some dependencies that will make the project assert.&nbsp;</p> [quote user=""]<br />2. Is it possible to operate Reg0 of nRF52840 in LDO mode by appropriate means using the current nRF Connect SDK?[/quote] <p>Using nRF52840 with LDO is fully supported. You just have to make sure that the DC/DC is not enabled in the project configs. Have you tried this?</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
