powering with 5v

The "Eleven" is our Uno-equivalent Arduino-compatible board, but with a number of improvements including prototyping area, a mini-USB connector, LEDs mounted near the edge, and the D13 LED isolated using a FET. [Product page]

powering with 5v

Post by kitbots » Mon Nov 12, 2012 12:29 am

I've set up dual DMDs controlled by my Eleven. The DMDs are powered via a small 5v power supply. I'd like to power the Eleven from this same power supply and I see the USB connection supplies 5V whilst the separate power plug wants 7 - 12v. I could just get another USB mini plug and connect it to 5v but are there existing pins on the board I could use instead? I see 5V and Gnd pins on the "power" six pin connector. Could I just connect via them?

Yes you can.

The 5 volt rail is common to the entire circuit, so if you apply power to that rail, you can power the microcontroller.
