    Все дошло в целости и сохранности. Фото прилагаю. Снизу индикаторной платы - царапины, поэтому ставлю четыре "звёзды".

    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 whenever one of the other LEDs is commanded on. The 2 LED banks are a bit mis-aligned, but this is just cosmetic. A real bargain to keep around for Arduino projects & tests.

    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

    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!
