Not super easy to get setup on Arduino Uno but its working great. I learned the length of hookup wires make a difference. Longer wires (1 foot or so) caused ghosted letters on the display. Here are the critical lines of code: #include <hd44780.h> #include <hd44780ioClass/hd44780_I2Cexp.h> // include i/o class header hd44780_I2Cexp lcd;

Works perfectly, reduces the number of pins used on the mcu. Fits directly on to the back of the LCD display. Libraries are available for Arduino.

I was building an external LCD display to use with my Odroid-C4. I needed an I2C interface. This product provided a reliable circuit board, a pinout description to assure compatibility and easy installation. I just don't like the external power pins for backlight since they are extending beyond the board and don't allow for dynamic controls. I ended up using a 2N7000 with a PWM to control the backlight.

Can't get these to work. They probably do work but I must not have correct library, though I used the libraries they say to use.

After previously purchasing a 20x4 I2C character LCD - also from Hiletgo - I wanted to dive deeper into the world of I2C communications, and I thought that this would be a great companion to the 16x2 character LCD that was included with my Elegoo Arduino UNO starter kit. I had a little bit of trouble with adding solder to the jumpers that assign an address to the modules, mainly because my soldering iron tip was too big, but I eventually was able to set the modules to the addresses that I wanted; I set one to 0x26 and the other to 0x25 to avoid conflicts with the 20x4 display, which I left at the default 0x27 address. Once the custom addresses were set, I proceeded to test the modules using the I2C scanning sketch for Arduino, and they both showed up with the addresses that I wanted. After adjusting the contrast, I wrote up a quick sketch to do some further testing, and both modules did their job and did it quite well. I removed the jumper for the backlight and replaced the jumper with a potentiometer for easy brightness adjustment.
