I LOVE the quality of your products, but I have one big problem with using some of them. Mounting holes...

A good example is the DFR0626 MCP23017 board. It only has 2 mounting holes and lots of pin headers. The board, at least for my uses, needs 4 supports.

Hi Alessandro,
thank you for your contact.
The mounting holes dimension is always marked in the schematics, but these may be something wrong with the schematics download link.
We will check and update it ASAP. And please note that the mounting hole dimension is 3mm.
Thank you for your feedback!
