That sounds like a very simple suggestion Paul. I am actually going to power my IOIO from a 24V supply, so I have an Orion 24/12-5A DC-DC converter to take me down from 24 to 12. The converter is supposed to handle transients very well, especially transients from vehicles. My VREG blew when I hooked it up to the DC-DC converter running from a 24V bench. So I was really surprised when the VREG didn't survive as I expected a very clean output.

To give some headroom over the phone's charging circuit. -- You received this message because you are subscribed to the Google Groups "ioio-users" group.
