-Small 1.8" (160x128) and 1.44" (128x128) TFT displays with ST7735 controllers have been available for a while now. They are only slightly more expensive than the very inexpensive [[arduino:displays_for_classic_arduinos:nokia_5110_displays_and_classic_arduinos|Nokia 5110]], and are about the same size, though with greater resolution.+These small 1.8" (160x128) and 1.44" (128x128) TFT displays with ST7735 controllers have been [[https://www.ebay.com/sch/i.html?_odkw=1.8%22+tft+ST7735&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.X1.8%22+tft+display+ST7735.TRS0&_nkw=1.8%22+tft+display+ST7735&_sacat=0|available]] for a while now. They are only slightly more expensive than the very inexpensive [[arduino:displays_for_classic_arduinos:nokia_5110_displays_and_classic_arduinos|Nokia 5110]], and are about the same physical size but offer color and greater DPI.
  
 One of the concerns with with TFT displays is that they are data gluttons, meaning they put a lot of stress on a piddly Uno/Nano/Pro Mini with regards to memory consumption, processing time, and data transfer time. However, it's not unreasonable to hope that a really small TFT display might still be workable, so I cobbled together some tests to see if that might be the case with these little displays. 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. One of the concerns with with TFT displays is that they are data gluttons, meaning they put a lot of stress on a piddly Uno/Nano/Pro Mini with regards to memory consumption, processing time, and data transfer time.

 The Adafruit library with its default font performs and looks almost the same as the Arduino TFT library. The Adafruit library with its default font performs and looks almost the same as the Arduino TFT library.
