The Raspberry Pi four is a good little beast, however Tyler Ward recognized a flaw within the USB Kind-C connector. The Raspberry Pi Basis confirmed to TechRepublic that the design flaw is actual, and that your Raspberry Pi four won’t work with all USB-C cables.
It’s not likely a dealbreaker, however you’ll be able to 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 will not be powering up, now you already know why.
The Raspberry Pi Basis has launched the schematics of the board. And there’s a lacking CC resistor that permit subtle chargers negotiate present with the gadget.
On condition 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 need to use 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.
Happily, it doesn’t harm the Raspberry Pi four and it doesn’t create any fireplace hazard. The gadget simply doesn’t energy up.
“I anticipate this shall be fastened in a future board revision, however for now customers might want to apply one of many advised workarounds. It is shocking this did not present up in our (fairly intensive) subject 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 superb for the previous couple of weeks.
