 In order for the selected SMA socket to fit, the PCB should only be produced 1.0mm thick. With 29x18mm, the module looks quite handy. Produced by [[https://jlcpcb.com|JLCPCB]] it costs a little more than usual because I used //Castellated Holes// so half holes for the module connections. I definitely recommend ordering a stencil, otherwise it will be even more fun when you paste it. Here is the 'paste' result with stencil: In order for the selected SMA socket to fit, the PCB should only be produced 1.0mm thick. With 29x18mm, the module looks quite handy.
