Run two Charlieplex grids from a single feather

Post by Gaff »

I have a plan for a wearable project that requires moving eyes. I was thinking of using the Charlieplex displays for this (the oleds look great but are considerably more expensive!).

Is it possible to run two feather wing Charlieplex displays from a single feather device? How much wiring would I need to do? Does the feather have enough power to animate two displays? Where can I look for more information?

Many thanks!

Should be possible. You can change the i2c address on the displays.
