Hi ! Apparently this model is not available anymore on the adafruit website. I don't know if it's out of stock because it's discontinued or any other reasons. For official support I really need something widely available, not discontinued devices. I only found 1 seller here in France with very limited stock.

Due to the very limited availability this does not make it a good candidate at this time. If your a little into MCU dev, you can follow the standard protocol available here it's made to be portable to any platform supporting native usb and PID/VID customization : https://manual.simhubdash.com/
