Hello, I’m wondering if anyone has any experience with surface mounting the XIAO nrf52840 to a PCB. I’m trying to use it for a wearable and so avoiding the thickness/height of headers would be good.

Hi there, So mostly for by hand, but you’ll need to apply paste to both the stencil for the board and on the Xiao’s Batt Pads Only… YMMV but I get :100: percent success when applying this tech. :crossed_fingers: HTH GL :slight_smile: PJ :v:
