nRF52811 replacement over nRF52832 plug-and-play ?

[StephaneJ]

Hi,

Our entire board is running around a nRF52832. Recently it has been difficult to find some of these SOC. Is it safe to replace it with the nRF52811 without changing the board layout and the firmware ?

Thanks !

Hi

Depending on what functionalities you need from the SoftDevice I would suggest looking at the S112/S113 SoftDevices for nRF52811, as the S140 will take up a lot of RAM and Flash memory on the nRF52811, which is already rather restricted with its 192 kB flash and 24 kB RAM., so the room for application and bootloader will be limited if you opt for the S140.

As for how to edit the RAM and Flash memory, please check out our guide on the matter here.

Best regards,

Simon
