Different VCCO voltages

Post by nward » February 4th, 2015, 7:57 pm

I would love, in a future version of the Mojo, if the VCCO lines were not all tied to 3v3.

Perhaps the DAC on the ATMEGA can generate different voltages for each bank, or something along those lines?

I'd love to be able to use LVDS_25 stuff, but can't :-(

Thanks for the suggestion. We could have a solder jumper to possibly select the bank voltage. You couldn't use the ATMEGA DAC since you need a substantial amount of current (VCCO drives the IO pins).
