Banggood

Qualité acceptable, semble robuste, conforme à la description, emballage antistatique B-D

muito bom

Complete & independent control over all 7 segments, decimal point and auxiliary LED for each of eight segments. This allows for limited alphabetic characters (see photos). Be sure to use pull up resistor for reading keys. Unit is capable of reading any combination of key presses, so 256 possible input patterns are possible. However, with the standard library, I found the key reads to be a little erratic, so I stick to just single button patterns. For some reason, LED #1 lights at half brightness

Quality is good no major defects. Works fine I had to change some things in a library for Arduino to work correctly with an ESP8266. Runs fine from 5 or 3.3v

Good quality and nice low price. Great for working on and gaining experience with Arduino.

Quickly got up and running. 3 wires communicated all of the features on the board. Great way to add a ton of input and output for only using three Arduino pins. Good quality. Mine worked with no issues.

Package arrived to Hungary in two weeks. The module is very versatile, can be used as control and feedback panel for a bunch of projects. Also it is much cheaper then the sum of the parts it is made of. Totally satisfied with it!

Moduł przydatny do Arduino. Dobre wykonanie, luty ładne.

not configured same as arduino standard libraries so not all examples works but is exactly what you pay for so yeah.

I received it on time I ordered it by banggood because it is the cheepest through Online shopping. Later on I will test it.
