Good working well 💯

Very bright display, needs 5V (and 5V logic commands) to work. Sensitive to the timings, when using a level shifter.

perfetto

Não testei ainda, mas parece de boa qualidade

Works as discribed.

У RobotDyn всегда все в порядке с качеством.

Looked great, but numbers were disappearing after a few seconds. Also couldn't use multiple Displays parallel. After searching found out that the Arduino delay function shouldn't be used, which is a problem. Library also not available so easily, different libraries but no one works without problems.

very good
