Customer Reviews
This works great with the i2clibraries.i2c_lcd class in Python. I tried it on 3.3v, but it needs the 5v. The backlight comes with a jumper cap, but I swapped it for a 10k pot, so now I have brightness control as well (see pic). And, its bigger than you expect, especially after using tiny oleds.
Nice bright display. Unfortunately it didn't last- it lost most of the characters. Now it is a 2x8 display.I restored the rating to 5 stars because further investigation showed it was an over voltage condition that damaged the display. Would recommend this product over the other sellers because the serial interface is already soldered in place, so saved a few minutes. Plus, a better price.
Replaced a 16x2 Lcd with this and I love it! Installing and modifications of the arduino code was a breeze. Used the LiquidCystal_I2 library. Example sketch included a scanner for finding the address. (0x27 on mine). If you are using a 16x2 this is a great upgrade!
Works fine. I did not need, nor want the feature of the IIC board, so I removed it and used the display as a parallel type.
As an I2C device this was a no brainer and didn't consume any pins on my Arduino since the I2C bus is shared with several other devices. Once you adjust the potentiometer for the brightness it is very nice to read. It needs a different library than its 16x2 cousin but that was a breeze to find and install.
It’s great I2C, safe a lot of pins with it
No issues with this. Using it with Arduino Uno. Almost plug and play.
Needed to adjust the potentiometer on the back to get it to display but works good for the price.
great buy
The first was defective. The second is great. The I2C address in your program may need to be adjusted
