ThinkInk current draw issue

Post by Rickhtoo2023 »

Hello, need some help on ThinkInk products current draw. We have 2 Arduino Pro Mini attached to 2 displays, one is the 2.13" mono display, and the other is the 1.54" mono. We are powering both with a 3.3 volt coin battery, and want to use the 1.54" display because of size restrictions. The problem is, both are drawing about 7 ma while processing, and the 2.13" display draws only a couple of ma more when updating. However, the 1.54" display draws around 50 ma during updating. Why does it take so much more to update the smaller display? Thanks for any assistance you can provide.

Rick
