The Raspberry Pi 4 doesn’t work with all USB-C cables

The Raspberry Pi 4 is a good little beast, however Tyler Ward recognized a flaw within the USB Sort-C connector. The Raspberry Pi Basis confirmed to TechRepublic that the design flaw is actual, and that your Raspberry Pi 4 won’t work with all USB-C cables.

It’s probably not a dealbreaker, however you may anticipate a future board revision with a correct implementation of the USB-C protocol. But when you end up scratching your head and also you don’t perceive why your Raspberry Pi shouldn’t be powering up, now why.

The Raspberry Pi Basis has launched the schematics of the board. And there’s a lacking CC resistor that allow refined chargers negotiate present with the gadget.

On condition that USB-C is an advanced connector, some cables are electronically marked, which implies that they’ve an built-in chip to assist a variety of units.

As an illustration, you need to use a MacBook Professional charger with loads of USB-C units. The charger simply figures out how a lot energy it must ship.

However the Raspberry Pi 4 doesn’t assist electronically marked cables, equivalent to Apple’s USB-C cables or Google’s Pixel 3 cables. The gadget is incorrectly recognized as an audio adapter accent.

Happily, it doesn’t harm the Raspberry Pi 4 and it doesn’t create any hearth hazard. The gadget simply doesn’t energy up.

"I anticipate this will probably be mounted in a future board revision, however for now customers might want to apply one of many instructed workarounds. It's stunning this didn't present up in our (fairly in depth) subject testing program,” Raspberry Pi Basis founder Eben Upton informed TechRepublic.

A easy workaround is to purchase a non e-marked cable or charger. The Raspberry Pi Basis is promoting an $8 USB-C charger as an illustration. In my testing, it has been working nice for the previous couple of weeks.
