I built an interposer board for the photon P1 Module.
Reasons I did this:
- P1 module does not have castellated edges, making DIY assembly very difficult.
- Not possible to debug a DIY-P1-development prototype board independent of P1 Module, I.e. one cannot have a prototype board where you can simply plugin and pull out the P1 module.
The interposer board (image included) has eagle footprint I can share that you can use in your prototype board. You can also use 1mm pitch pin-row-header and solder to the interposer board so you can plug into your own DIY-prototype board and pull out as needed…
Note that the pads on the interposer board that mate with the pads of P1 module, have through holes in them, so you can solder P1 Module pads to the interposer board from the back – as shown in the pic attached.
It is not intended for production run. If anyone is interested, please contact me…
