Does anyone know if the GP32 has an on-board DC-DC converter to kick the 3V upto 3.3 V, given that all the devices on the PCB are 3.3V ?, I have a stack of 3.3V regulators and I would like to use one in my homebrewed PSU.

Also does anyone know if the unused pins in the processor are floating, or are they tied to the power rails to keep the noise down?

Thanks.
 
a DC to DC converter would be a huge waste of energy just to get .3v out the card will run at 3v and even alittle bit lower.

If you wanna use the 3.3v dc chip then use it in a psu but it be a waste if it was running off batteries.

Sorry i dont know whats done with the unused pins

:ph34r:
 
Thanks,

I am not using my GP32 for gaming, I'm using it as a control computer.

For my application I don't need batteries but I do need stable I/O so 3.0v is skating on the edge for me, the core runs at 1.8v but the I/O and the analog block runs at 3.3v +- 0.3.
