  1. Man, that’s a slllloooowww refresh time on the e-paper display. If it were 500 msec or so, it’d be obnoxious, but usable.

    1. There was a “partial refresh time” of 0.3 second in the table. But I’m not sure what that means since i guess the time will depend on which pixels are updated.

      The refresh time will not always matter though. For example, if you use it as a badge, or price tag that you may only update daily or every few days, a few seconds delay is not that much of a problem..

  2. I purchased one of these boards from Banggood. However it differs from the one pictured in that instead of a slide switch on the right side above the battery connector, there are four blue LEDs. The top one blinks all the time and the other three are always illuminated. Is there any way to program these LEDs?

  3. Hi,

    I have this board from Tindie but I can not compile Arduino code. I get an error in “boardef.h” —“please select board type”. Any idea?

    Thanks,

    1. Hi Ivan,
      You must change the macro definition in board_def.h according to the corresponding layout and screen, and change the version to be used to 1.

      #define TTGO_T5_2_2 0
      #define TTGO_T5_2_3 1 //Example
