I'm working on a project that uses these bluetooth modules:
It will be a step counter for my daughter for jumping rope. She will have a wearable that communicates with display. The bluetooth modules have a 90 degree header soldered onto them. Right now I have it breadboarded with the bluetooth module standing vertically in the breadboard. For the wearable the final version will be a PCB prototype board with soldered connections. I'm trying to find a riser of some sort that I can solder to the prototype board where the arduino Pro Mini will be that will let me then stack the bluetooth module so that they are stacked in horizontal layers. Does something like that exist? All of my searches are finding riser cards for computers.
