The Raspberry Pi four is a superb 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 four may not work with all USB-C cables.
It’s probably not a dealbreaker, however you may count on 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 you realize why.
The Raspberry Pi Basis has launched the schematics of the board. And there’s a lacking CC resistor that permit refined chargers negotiate present with the gadget.
Provided that USB-C is a sophisticated connector, some cables are electronically marked, which implies that they’ve an built-in chip to assist a variety of gadgets.
As an illustration, you should utilize a MacBook Professional charger with loads of USB-C gadgets. The charger simply figures out how a lot energy it must ship.
However the Raspberry Pi four doesn’t assist electronically marked cables, resembling Apple’s USB-C cables or Google’s Pixel three cables. The gadget is incorrectly recognized as an audio adapter accent.
Luckily, it doesn’t injury the Raspberry Pi four and it doesn’t create any fireplace hazard. The gadget simply doesn’t energy up.
“I count on this will likely be mounted in a future board revision, however for now customers might want to apply one of many advised workarounds. It is stunning this did not present up in our (fairly in depth) area testing program,” Raspberry Pi Basis founder Eben Upton instructed TechRepublic.
A easy workaround is to purchase a non e-marked cable or charger. The Raspberry Pi Basis is promoting an $eight USB-C charger for example. In my testing, it has been working nice for the previous couple of weeks.
