AZDelivery Compatible with HD44780 LCD Keypad Shield 16x2 LCD1602 Expansion Board Module Display I2C IIC 5V compatible with Arduino Including E-Book!

More reliable than trying to connect a display using a breadboard -- and the buttons come for free. (One button was unreliable and had to be replaced, but that wasn't a problem).

I purchased these to use with the Arduino Mega but so far they haven't been compatible. It is probably me but I won't buy any more

It says clearly in the advert that you get a free ebook with all the info you need. Rubbish This is part if the reason I purchased this

The item description boasts a free EBOOK full of easy start examples, code examples and layouts.Great idea youy may think. Only this is a virtual EBOOJK, a figment of AZDeliveries imagination.Usually you would go to the vendors website and download the relevent ebook.This time the website reports that it is out of stock??? How can a virtual / digital document be out of stock?I contacted AZDelivery support who told me that not so much out of stock but not yet written. More... no expected publication date was available.They did try to remedy the situation by availing me of the datasheets, pinouts wect and I got the impression I was being told to do it myself.Even more it aoppears that they just add this FREE BOOK boast to all items they sell wether they exist or not.My conclusion therefor is to check there promises first and see if the promised items exist?Or ultimately if you cannot trust the sales pitch, go somewhere else. Try Pimoroni or Pi Shack to name just two. They at least do provide what they promise wether it be code example or tech data

The package was damaged, pins arrived bent, and the tensiometer, by default, was configured so nothing would appear on display.

The only reason I bought this was because of I2C interface which it doesn't have and you need to buy it separately.
