The Raspberry Pi 4 is a great little beast, but Tyler Ward identified a flaw in the USB Type-C connector. The Raspberry Pi Foundation confirmed to TechRepublic that the design flaw is real, and that your Raspberry Pi 4 might not work with all USB-C cables.
It’s not really a dealbreaker, but you can expect a future board revision with a proper implementation of the USB-C protocol. But if you find yourself scratching your head and you don’t understand why your Raspberry Pi is not powering up, now you know why.
The Raspberry Pi Foundation has released the schematics of the board. And there’s a missing CC resistor that let sophisticated chargers negotiate current with the device.
Given that USB-C is a complicated connector, some cables are electronically marked, which means that they have an integrated chip to support a wide range of devices.
For instance, you can use a MacBook Pro charger with plenty of USB-C devices. The charger just figures out how much power it needs to deliver.
But the Raspberry Pi 4 doesn’t support electronically marked cables, such as Apple’s USB-C cables or Google’s Pixel 3 cables. The device is incorrectly identified as an …read more
