Layers and Stackup

MattHorton

Is there any reason not to use a 2-layer board for the nRF9160? Is a 2-layer or 4-layer board recommended? My current board is just 2-layer and I haven't had any issues with it but I wanted to check to see if anyone else has any input.

    Hi,

     

    nRF9160 needs a (mostly) solid ground plane, if you can keep your bottom layer free from components and trace routing it should be fine to use a 2-layer board. Feel free to submit it here if you want an evaluation, you can make a private ticket if you do not want anyone but Nordic support engineers to see your design.

     

    Best regards,

    Andreas
