With this product, you can secure board (PCB) having 4mm holes. The adhesive under the feet can be used to affix the board everywhere.
By removing a small part of plastic (with your cutter) you can even reduce the minimal diameter to ~3mm wich fit perfectly on board having 3.2mm holes.
This allows you to use it with Arduino board (holes of 3.2mm) or a L298 H-Bridge board (3.3mm hole).
Unfortunately, it would not be possible to use them with Raspberry-Pi because their holes are as small as 2.7mm diameter
- Height: 5mm
- For holes: diamètre 4mm (3.2mm by slicing an unwanted part on the holder)
- See the pictures for dimensions
