https://devzone.nordicsemi.com/f/nordic-q-a/11494/ground-restriction-nrf52Hi, We are using the nRF52 chip with other RF modules. Is there any ground restriction that we need to be aware of in our design so that there is no interference ?

Make sure that you use plenty of vias to achieve this. If the other RF modules are very sensitive it might be required to make via-stitches to separate the different modules, this is not a direct requirement from the nRF5 series.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>
