Powering Metro Mini 328 From Battery

by LimeAY on Tue Jan 29, 2019 2:08 pm

As the title says, I need to power the Metro Mini Microcontroller from a 5V battery.

How would i go about doing this?

Do i need to use a voltage regulator or does this controller have on built in if i were to use a 9V battery?

If so is there some form of adapter to allow me to power it with this battery type, i.e 9V battery to Micro Usb?

Any help would be great thanks!

If you have a regulated 5v source, you can feed it directly to the 5v pin on the Metro - or via the USB jack.
If you have a higher voltage source (e.g. a 9v battery), connect it to the VIN pin. There is an on-board 5v regulator.

The VIN pin can handle from 6v-16v. Lower is better since higher supply voltages will cause the regulator to get quite warm.
