I want to double check on the mechanical spec. As it is written, the CSI port is 20mm from the bottom of the board. It's quite in the way, especially with respect to real estate for connectors exiting on the same side as the USB connector. For my board, I moved the CSI connector down about 10mm, which allows me to put three connectors on this side, but still lines up east-west with the CSI cable and easy feed through the slot. See image below.
What I want to check is if the mechanical spec is so rigid that I cannot call my board a HAT. If not, I can call it 'HAT-like', I suppose. Right?
