Modules working fine in the beginning, but after some time the LED intensity decreases and a random 7 segment element stops working. After some more time, the whole module shuts down. After a reset, the whole thing starts over again. I'm using an original Arduino and the tm1638 library and the wiring are like in one of the several youtube videos about this module.

Work as expected, good quality
o.k.
Prodotto di per se valido anche se di non facile utilizzo. Alcune librerie disponibili non sembrano funzionare correttamente a meno di laboriose ricerche su internet. Ha funzionato solamente con istruzioni ad hoc in linguaggio C
And everything works with both Arduino and ESP32.
Well built and coming with cable once plugged in it worked immediately. Very easy to communicate with with ready sketches available..
Everithing OK
