There are already two entries for this module: https://www.modulargrid.net/e/sleepy-circuits-hypno-hdmi-expander-panel-diy and https://www.modulargrid.net/e/sleepy-circuits-hypno-hdmi-expander. Do we really need another one? ò.Ô

this is the usb expander not the hdmi one you linked to

Err, now I feel like a fool... Indeed this is USB, thanks for clarifying this!

This module is listed as available, but it is not. I've been watching the product page for over a year and it's never been in stock.
