Does Adafruit stock newer Raspberry Pi B version that can be

Post by jahuber »

I have read that the newer revisions of the Raspberry Pi B can be powered through the standard USB port instead of the dedicated micro USB power connection. Does Adafruit carry these newer versions?

"Fresher" Pi's now have either 0-ohm resistors on F1/F2 (Model B Revision 1.0 + ECN0001) or no F1/F2 pads at all (Model B Revision 2.0)... With those polyfuses gone, the Pi can be powered via it's USB host ports as an alternative to the micro USB jack. "

Thank you for your time.

These never sit on the shelves for long, so what we are shipping should be up-to-date.

I was just wondering about this myself, but looking for an alternate point to insert 5V directly onto the board using a different connector.

Technically speaking, sourcing power with a Type-A USB plug is not a valid configuration since the danger of plugging it in to a powered Type-A receptacle means the 5V supplies on each end will fight each other...not good. But if you keep that in mind and ensure that will never happen, according to the schematics (if I haven't missed anything)

the USB-A port can be used to power the board as well as the other USB-A port. They are all wired together.

Sourcing power from an OTG microB USB cable is perfectly valid and good also.
