Well, since EVBOT having transition state currently, here's alternative solution for you, EPOWER people.

Since controller accepts controls from PMBus, attached Raspberry Pi can talk to EPOWER and adjust voltages. Voltage range is 0.6 to 2.0V

 

Tested with Model B Rev2.0 (not plus), but should work with any Pi.

 

Details in this article for those who interested.

Try it, and let me know if any problem :)

 

Also old-school hardware-only way with trimpot resistor is covered too. :rolleyes:

 

:D
