IPS Display 1.22 inch

Grove - IPS Display 1.22 inch (Seeed-Studio)[edit]

Caractéristiques[edit]

RGB OLED Display 1.22 <ST7789> v1.0
écran à cristaux liquides de 1,2 pouce
240 x 240 pixels
l'écran peut afficher jusqu'à 65 000 couleurs RGB
3.3V or 5V
l'écran utilise le ST7789 comme circuit intégré de pilotage
l'écran utilise la technologie IPS. Quel que soit l'angle de vue, l'expérience visuelle est quasiment identique sous tous les angles.

Sa bibliothèque de pilotes open source et son code d'exemple facilitent la prise en main

Communication[edit]

D7 (D7/D8) port
