 The 1.3" size in particular is an attractive alternative to the [[arduino:displays_for_classic_arduinos:nokia_5110_displays_and_classic_arduinos|Nokia 5110 display]] in that it isn't surplus and offers a more modern appearance. They are also a promising alternative to [[arduino:displays_for_classic_arduinos:1.8_and_1.44_tft_displays_and_classic_arduinos|1.8" and 1.44" TFT displays]], whose data requirements leaves speed wanting with the wimpy little Uno/Nano/Pro Mini. The 1.3" size in particular is an attractive alternative to the [[arduino:displays_for_classic_arduinos:nokia_5110_displays_and_classic_arduinos|Nokia 5110 display]] in that it isn't surplus and offers a more modern appearance.

-In the tests that follow, I am striving to answer first whether the rendering updates will be fast enough for reasonable use and second whether there will be any memory left to do anything interesting. They are certainly fast enough, but the required program storage and dynamic memory isn't trivial.+In the tests that follow, I am striving to answer first whether the rendering updates will be fast enough for reasonable use and second whether there will be any memory left to do anything interesting.
