https://youtu.be/xjt1LPbEKvQ?t=337
Organize projects with these modular Lego base plates for STEMMA boards! These 3d printed holders feature built-in standoffs for press fitting the PCBs.
It’s a nice way to secure them without screws or adhesives.
STEMMA board and sensors allow you to plug-and-play together various devices and accessories, without any soldering!
In this project, we'll build Lego base plates for all of our STEMMA boards! We designed several different sizes to to fit all of our boards!
On the bottom are tubes that are designed to fit onto LEGO compatible bricks.
The clearance in between the PCB and holder allow space for components on the bottom of the PCB.
We also designed lego plates for a couple of components like Feather boards, battery pockets and a slide switch.
All of the base plates print will out any supports and the built-in pegs allow board to simply snap to place without any additional hardware.
