WS2812B/NeoPixel LED Strip Zweck
Adressierbare RGB-LED-Streifen für Ambiente-Beleuchtung, Effekte, Benachrichtigungen oder dekorative Anwendungen. Anschluss Stromversorgung
⚠️ Wichtig: LED-Strips brauchen viel Strom!
Pro LED: ~60mA bei voller Helligkeit (Weiß)
30 LEDs: bis zu 1.8A bei 5V
Ab 10+ LEDs...
