Adapting an Adafruit Trinket for use with Snap Circuits

Similar projects worth following

The biggest change from the Gemma to the Trinket is a more square-like layout for the snaps. This is shaped more similarly to the majority of the official components.

Also of note is the Trinket has mounting holes (albeit teeny tiny ones) which means I can bolt the board on instead of gluing it down.

Those of you familiar with Trinkets will notice that I haven't exposed all of the pins on the trinket to snaps. This choice was largely to limit the final size of the plate. Since I decided to expose only a subset of the pins, I had to decide which ones it would be. In the end I couldn't make up my mind all the way so I put female header on my trinket and plug into it with wires coming off of the snaps. This way it is reconfigurable.

  • 1 × Some coper wires
  • 2 × 5 pin Female header (optional)
  • 4 × Sets of Teeny Tiny nuts & bolts which incedentally came from Nuts & Bolts
  • 6 × SZ 2 Sew-On Snaps (male side only)
  • 1 × Adafruit Trinket

    The glue is dry. I did a bit more unsnapping/snapping abuse testing, one of the snaps I can see is a bit more loose than I'd like but all of the others are holding strong so far. I'll be brainstorming some alternate (hopefully more stable) methods of affixing the snaps to the plate.

    Got a chance last night to try out last night, and I am happy to report that it blinks!!!

    I glued down half of the snaps last night using E6000, left them clamped over night and they are holding up nicely to some snap/unsnap abuse. I just got done gluing the other half of the snaps. So tomorrow night I should have a complete board ready to start playing with.
