The information currently listed here should be enough to be able to build the picoTracker "portable" if you've done projects like these before.
Here are linked examples of sources for the components, but they can be purchased in many different places and the listing below is not an endorsement or recommendation of any particular vendor.
- PCBs and PCB SMT assembly can be done at JLCPCB
- ILI9341 2.8" NO TOUCH NO PCB display
- 3.7V 700mAh 802535 Battery
- 9 x Cherry style switches
- M3 & M2 screws
- Optional DSA low-profile Keycaps
- 3D printed case
- Optional 3D printed keycaps
Instructions on how to build the kit can be found on the original blog post.
There is also a great video by @FloydSteinberg showing how he built a picoTracker portable from a kit.
There is also another video on the final part of the assembly that you may find helpful.
Few tips:
- Be VERY careful in aligning and soldering the LCD to the PCB, this is by far the hardest part of the whole build. Here is a useful video on this topic
- Use some thin double sided tape to stick down the LCD flexcable before soldering, the whole LCD after soldering (your LCD may already have tape applied to it) and the battery to the PCB.
