Le Le Click Board™ 7-Seg RGB est doté d'un affichage numérique à 7 segments en couleur. Le Click Board est conçu pour fonctionner sur une alimentation 3,3 V ou 5 V. Il communique avec le microcontrôleur cible via la broche CS et PWM sur la ligne mikroBUS™.
Le 7-Seg RGB Click Board™ peut être connecté en chaîne, afin d'afficher un plus grand nombre de caractères. Contrairement aux écrans 7 segments classiques, vous pourrez utiliser plusieurs couleurs sur l'écran.
Display Features
Each segment has R, G, B LEDs that can be adjusted in 255 steps and therefore 16,581,375 colour combinations are available for each segment of the digit on the display.
Also, the ability to control the brightness of all the LED's is driven at 255 steps. It should be noted that brightness values above 80 should rarely be used.
