Teensy 3.2/4.0/LC soldering jig

thingiverse

I love PRJC's Teensy 3.2 modules, but soldering them and making sure all of their pins are well aligned/positioned is tricky (especially, in my experience, the bottom SMD connector.) I've designed this jig to make installation of the pin headers and bottom SMD connector easier without risking melting one of my solderless breadboards. I've found positioning and alignment of the bottom connector to be the most problematic, and didn't have much luck 3D printing alignment pins/holes/etc. (they're too small, and I didn't want to be bothered with a nozzle change for something this trivial) so I instead used standard 2.54mm/0.1" pin headers and female receptacles to handle positioning for me, with some support pegs on the jig to keep things level. Once the bottom connector is installed, it's just an issue of cutting pin header strips of the correct length to drop into the channels in the jig and soldering them from the top-side, easy! The model shows a Teensy 3.2, but it should work with the slightly different footprint Teensy 4.0 by choosing different pins to align the bottom connector (see instructions below.) I'd love to hear more about how to make this jig better, it still takes a little work to attach the bottom connector so if you have ideas on how to make it (or anything else) better please let me know!
