Two "CC" pins on a USB-C port are supposed to each get their own 5.1K ohms resistor, but Raspberry Pi came up with its own circuit design that allows them to share a single resistor. This is not a ...

Tyler Ward and others have discovered that the Pi 4 isn't using a properly designed USB-C port. Instead of giving two pins their own resistor, Raspberry Pi created a custom circuit that has them ...

The official Raspberry Pi USB 3 Hub features four USB-A 3.0 ports, which are backwards compatible with USB 2.0, plus an extra USB-C port that can power the hub if required. The new hub is ...
