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

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!

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. 👍

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.

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.

I bought four of these for a project, using them together with Micropython on a Raspberry Pi Pico.The devices consist of a main board plus a small "backpack" board with the I2C circuitry. The backpack is soldered to the main board. On every one of the boards I received, the backpack was skewed at an angle to the main board- see picture (I have some of these boards from a different supplier and the backpack boards are parallel with the main board as they should be). Also, every one of the boards had some bent pins.On the other hand, all the boards worked just fine. Also, the examples and libraries on the Freenove website are very useful.Docked a star for the poor quality control but otherwise all fine.

Use 5V

Display appeared to be packaged well with no obvious damage to the box or packaging, but when display was removed from the protective bag, it was obvious that the display has had something sharp in contact with the display. I hoped it was only damage to the protective film across the display, but when peeled off, it has gone all the way through and damaged the surface of the screen itself.Looking at the packaging and the location of the damage, I would say the damage happened before it was sealed in the bag. Disappointing!

Worked as expected and is of good quality.

Works great with no R3, easy to connect and put up messages within minutes!
