Usb alternate power supply

Parts Questions

Hi,

I’m wondering if I can run my MidiBox32 on power from another source than my computer. Maybe it’s a silly question but it would be extremely handy if I could use say for instance the power socket of an iPhone charger. I don’t want to try before asking about it since it might be totally stupid and the unit might die.

Thanks,

It says I can use a 7-10V and at least 500mA adapter. If the iPhone charger gives 5V, which I also get via the computer, and 1000mA it should be ok to use that then I guess. Am I right?

Yes, you can use a regulated 5V supply as well. In that case simply supply the power to J2 and not J1 (the voltage J1 goes through a rectifier and the voltage regulators which need a higher input voltage than the desired output). Be acreful with the polarity and read the sections on J2 on the core module page.
