Il display funziona perfettamente, è molto luminoso e compatibile con Arduino.
Per il collegamento con Arduino si può usare la classica libreria LiquidCrystal_I2C, io ho usato la versione scaricabile qui: https://github.com/marcoschwartz/LiquidCrystal_I2C
I due pin di segnale vanno poi collegati in questo modo: SDA --> Arduino A4, SCL --> Arduino A5
La luminosità del display è regolabile tramite un trimmer posto sul retro.
Attenzione: nel mio caso il display è arrivato con la luminosità impostata al massimo, in questo modo il display era tutto completamente verde e non si vedeva il testo visualizzato, facendo pensare ad un malfunzionamento... dopo aver abbassato la luminosità tutto funziona bene.
