0.49" micro OLED screens are remarkably low power

A hidden gem with our new e360 classroom loggers: the 0.49” micro OLEDs only draw about 3-400 µA and sleeps ~6µA! So you can have screen output like this for about same amount of power as an indicator LED and that means you can run them on a Cr2032!  Since they use SSD1306 controller they can be made to work with standard libraries provided you compensate for mis-match between the origins on screen and the origin in the controllers 1K memory.
