(SOLVED)Power ATOM Lite

[cepics]

Can I power Atom from grove and ext pin also?

[m5stack]

@cepics yes , you can use grove or ext pin to supply power for Atom. it max power consumption 1.5W

tnks a lot

it is possible via the ext pin for 5 volt or also the ext pin for 3.3 volt? (not using the Grove port)

@pepsi

you can see the sticker , the ext pin provided a 5V input pin. the ext Pin 3.3V only can output.

@m5stack We are talking about M5Atom here....

my question is indeed related to the Atom. the symbols on the sticker for the Atom only hold 3V3 and 5V not no arrow if it is input/output.
I'm looking for a project with the Atom to run off a LiPo battery.
A step down converter will work longer than a step up converter.
I know the M5StickC (i have a few), but i need a more robust power switch. and the stick does not have a breakout option for a switch.

@cepics ....sorry ...i placed the wrong picture。 but they pin function is same. 5V can input/out put. 3.3V can only output

[m5stack]

@pepsi ATOM ext Pins. 5V can input/out put. 3.3V can only output
