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! ### ⭐⭐⭐⭐⭐ Very nice display *by on Reviewed in the United Kingdom 11 September 2025* Excellent quality screen, very clear, no backlight flickering and well put together. I have it happily running off the 3.3V line on an esp32 s3. These are great for that retro LCD look! I have the refresh rate at 0.5 seconds for scrolling on the bottom line, the second and third lines change displayed data once every 5 seconds(offset from each other) and the time on the top line. All transitions are crisp and as good as could be expected from this type of display. Great for learning about displays and creating fun projects to display your data! ### ⭐⭐⭐⭐ Works well but difficult to set up *by on Reviewed in the United Kingdom 8 February 2024* 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. ## Frequently Bought Together - FREENOVE I2C IIC LCD 2004 Module, TWI Serial 20x4 Display, Compatible with Arduino Raspberry Pi Pico ESP32 ESP8266 - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Arduino Uno REV3 [A000066] --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/518883880-freenove-i2c-iic-lcd-2004-display-serial-20x4-screen](https://www.desertcart.pt/products/518883880-freenove-i2c-iic-lcd-2004-display-serial-20x4-screen) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-27*
