Worked fine at first attempt. Make attention to set appropriately the contrast on the trimmer: writings on display can appear so dim to made you think that it doesn't work. I searched for the address with an I2C scanner (code easily findable on Arduino site) and resulted for my item 0x27. To change address you need to solder jumpers on the A0-A1-A2 points near the trimmer. Funzionato al primo colpo. Attenzione a regolare il contrasto con il trimmer, perchè le scritte a display possono essere così

Received well in good order and well packed. Still need to test them

A perfect fit with 1602 lcd module requiring only 4 connections to drive it. Attaches easily to lcd making for a compact display module

interface i2c muito bom elimina muitos fios na hora de montar recomendo

Tutto ok, perfortuna c'era tutto nonostante la confezione fosse aperta!

excelente

Fonctionne parfaitement. A noté qu'il est important de savoir souder les pins sur l'écran d'affichage car les connections ne sont pas très bonne si on ne fait qu'insérer ce module sur l'écran LCD. Il est également possible de faire les branchement avec les fils mais c'est moins propre.

Nem volt időm tesztelni. Tápot kap. LED világít. :) I did not have time to test. You get power. LED lights up. :)

Save Digital pins on Arduino by using I2C Serial Interface on I2C Bus. See picture with 4xINA219 + 2 INA3221 and at the end , the LCD 1602 connected with this I2C Serial Interface

a perfect product with good properties. came in time, well packedý, it works well
