It’s quite convenient for beginners to call the built-in library Liquid Crystal compatible with Arduino IDE, no need to edit yourself. Working voltage: 5V; Contrast adjustable with a 50K potentiometer onside. To use the 3.3V backlight, just connect pin A to 3.3V, pin K to GND. Note: Solder the pin headers on it before using. Pins’ Function VSS: Connected to ground VDD: Connected to a +5V power supply VO: To adjust the contrast RS: A register select pin that controls where in the LCD’s memory you are writing data to. You can select either the data register, which holds what goes on the screen, or an instruction register, which is where the LCD’s controller looks for instructions on what to do next. R/W: A Read/Write pin to select between reading and writing mode E: An enabling pin that, when low-level energy is supplied, causes the LDC module to execute relevant instructions. D0-D7: To read and write data A and K: Pins that control the LCD backlight For more details, please click: http://wiki.sunfounder.cc/index.php?title=LCD2004_Module Package Included 1 x LCD2004(The Pin Not Included) Review: Excellent quality lcd - Worked great with the arduino liquid crystal library.

Build quality is excellent, very thick and bright. ### ⭐⭐⭐⭐⭐ Works Well *by M***D on February 16, 2023* Same library and commands as the smaller 16X2 that comes with the Arduino starter kit. ### ⭐⭐⭐⭐ no problems with the LCD *by C***L on September 9, 2017* The header pins that comes with this are really short. they are the same length on both sides. normally, when i put a header in something like this, the pins stick up a little bit out the top. i had to push the pins down through the plastic holder so they now sit flush with the top of the LCD board. the LCD itself works like it should. backlight adjustable. easy to setup with the LiquidCrystal library. --- ## 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.no/products/43935314-sunfounder-lcd2004-module-with-20x4-white-characters-on-blue-background](https://www.desertcart.no/products/43935314-sunfounder-lcd2004-module-with-20x4-white-characters-on-blue-background) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-17*
