Voltage in for MO

by Prwall on Fri Feb 01, 2019 2:31 pm

Hi, newbie here.

What’s the max voltage into the BAT pin on the Trinket MO? I suspect it’s just as it states in the board, 6V.

Trying to run with a 12v battery, what’s the easiest/smallest way to power the MO with this battery?

Thanks.

Depending on what else you plan to run from the Trinket you could use a resistor voltage divider or a small voltage regulator that can handle the 12-volt input.

Thanks for your reply.

It won’t be running much, just triggering the electronic speed control for an EDF motor.

A small regulator (https://www.adafruit.com/product/2236) is best. A Zener diode (e.g.) with series resistor would be second best. I would not go the resistive divider way.

Thanks for the help. Found a small converter prewired that will take in up to 24v in and put out 5v at 3a.
