FREENOVE I2C IIC LCD 1602 Module, New Type TWI Serial 16x2 Display, Compatible with Arduino Raspberry Pi Pico ESP32 ESP8266

After using the old how many pins 🫣 versions, going to their newer models has been a godsend, especially with the lack of extra wires around the breadboard. They are good quality and both of them work fine on my project. 👍

I don't usually review these small electrical components, but I feel I must commend the suppliers of this LCD module to provide a web link to a comprehensive set of instructions/tutorials/example sketches with their product. It's so rare these days to actually get any information on how to wire and setup these items, and you usually spend days trying to figure it out. Such a breath of fresh air to have the information given with the product - I wish every supplier did it. When I'm looking for Arduino modules from now on, this supplier will be at the head of the list.

The display itself is of good quality and when adjusted correctly, it's bright and sharp.Quality control was not 100% - the backlight brightness was turned up full, so that characters did not display at all. I thought it wasn't working until I figured that the backlight needed turning down.Software library on the Freenove website is impossible to install, especially for the STM32 series of boards.I tried with an Arduino Leonardo and found a suitable library to make it work.It's cheap for what it is, especially as it come with an I2C adaptor, so I guess a little inconvenience having to research the beast is acceptable.If I ever get it to work on an STM32WL55JC board, I'll probably buy a few more for further projects.

I bought this display to work with a Raspberry Pi Pico. Followed the instructions and it worked first time. Just watch out for the contrast adjustment on the back of the module.The display is supplied with patch leads to work with either a Pico with male header pins or a breadboard.The information in the ZIP file is very clear. Idiot-proof wiring diagrams, instructions for loading the Python driver file and example programs that work!

Great quality, just what I needed for my project

Great LCD's easy to wire and add to any config files.

Easy to use via i2c. Obviously only 16x2 characters so you need to be sure that is sufficient for your needs.Only minor gripe is that display is virtually unreadable without the backlight, which itself is quite bright. Would be nice to control brightness of displayed data.The only other thing to watchout for is that supply voltage needs to be 5v not 3v3. I didn't pay attention and initially used 3v3 from pico. Everything appeared to work except no data displayed. Everything else seemed to work, including the backlight. As soon as I switched to 5v, bingo.

When I used one of these last year I had to edit the examples quite a bit to make them work on a Pico.I ended up replacing it with a parallel port one, which was more wires but worked flawlessly.
