How standard are USB footprints
« on: January 04, 2019, 12:08:37 pm »
I have a bunch of USB devices at home that require frequent plugging in and out and moving around. As a result, in a number of locations I have a bunch of different USB cables at all times, to match each of the connectors. It would be interesting if I could change all of these devices to one single connector (preferably USB-C as the phone and laptops are by far the hardest to change).

So how standard are these footprints. Can I just get USB-C connectors with only the USB2 pins enabled?

Just replacing a Type B Micro socket by an USB C socket won't work - neither as host or device. You will need extra circuitry for making an old USB2 device USB-C compliant.

There is a lot of documentation to read. For a quick start:

USB Power delivery is a quite complex topic on its own with many 1000 pages of specification.
