Microview current draw @ 5V?

Hi all,

I haven’t found it on a datasheet yet. What is the Microview’s current draw when powered by 5V?

I realize that it’s dependent on OLED activity, but what’s typical / worst case ?

Thanks!

Hi Schema,

Display off, about 3uA

50% Display on about 11-13mA

100% Display on about 18mA

The current draw also depending on what is connected to MicroView, the efficiency of the loop().

Oh, that’s excellent, thanks.

I have an idea for an embedded application that only had 100mA current available - looks like I’ll have tons of margin. Will try it this weekend. Thanks!
