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

0 4

The Raspberry Pi four is a great little beast, however Tyler Ward identified a flaw within the USB Type-C connector. The Raspberry Pi Foundation confirmed to TechRepublic that the design flaw is actual, and that your Raspberry Pi four may not work with all USB-C cables.

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

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

Given 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.

For occasion, you should use a MacBook Pro charger with loads of USB-C units. The charger simply figures out how a lot energy it must ship.

But the Raspberry Pi four doesn’t assist electronically marked cables, resembling Apple’s USB-C cables or Google’s Pixel three cables. The machine is incorrectly recognized as an audio adapter accent.

Fortunately, it doesn’t injury the Raspberry Pi four and it doesn’t create any fireplace hazard. The machine simply doesn’t energy up.

“I anticipate this can be fastened in a future board revision, however for now customers might want to apply one of many recommended workarounds. It’s stunning this did not present up in our (fairly in depth) area testing program,” Raspberry Pi Foundation founder Eben Upton instructed TechRepublic.

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