Has anybody created a Teensy 3.2/3.5/3.6 carrier board that is soldered directly to the Teensy using pads with plated through-holes for soldering?
I have a larger board I embed Teensy 3.2 onto. To get easy access to the pads (both pin pads and the USB D+ and D-), I was considering I could use exposed pads with vias through them, so I could solder the Teensy directly to the carrier board. I don't need any routing on the carrier underneath the Teensy on the Teensy-facing side, nor any extra vias, so this seems to me like this might work better than soldering short wires or pins to Teensy. For alignment, I can use pins like the USB panel mount breakout board. (However, that board uses castellated holes to solder the D+ and D- lines to, not vias.)
Anybody done this yet? Experiences? Opinions?
The other approach I know would work, would be to use castellated holes on the carrier board. (It does not matter *which* board has the castellated holes...) However, it looks like inside castellated holes are problematic for the cheap prototype PCB makers, so I'd probably have to hand-file the castellations. I'd rather use vias/plated through holes instead, if that has a moderate chance of working.
