Featuring a user-friendly I2C interface and a vibrant blue backlight, this LCD is perfect for DIY makers and IoT enthusiasts looking to enhance their projects with clear, real-time data visualization. ## Description Product description Description The 2004A character LCD module is designed to display letters, numbers, symbols, dot matrix. It can display 4 lines of 20 characters. Support 4-bit and 8-bit data transfer mode. Features 20 Characters * 4 Lines, Character LCD module; Blue Backlight; 5V for Logic Circuit; Support I2C protocol; Default Register Address: 0x27; Backlight Adjust: Jumper; Compatibility Used for connecting Ar-duino and Raspberry pi and it can be used to display real time clock, temperature, humidity etc. (A potentiometer is also necessary to adjust the contrast. Working Voltage: Only 5V ) To get more information, please check our wiki wiki.52pi.com/index.php?title=Z-0235 Package Includes 1x LCD 2004 Module, 4x Jumper Wires Review: Just Works - A good 4x20 LCD with attached I2C controller. Although the picture implies that the controller can be removed, it cannot without unsoldering all the connections to the display itself. Functionally fine, but be aware that I2C LCD controllers are "slow" compared to the standard, multi connection (many wires) method. One may want to try various libraries if refresh speed is an issue. Review: Use a resistor if screen isn't clear - I had to buy this for a college project, and the screen worked. At first, the screen was too bright and reading the text was kind of tough, but using a resistor made it crystal clear. ## Features - The LCD has always been a device that acts as a window in human-computer interaction. For example, the prompt window on some instrument devices, the temperature and humidity prompt box, the device running status monitor, and the prompt screen of the counting device all have LCD figures. - The common LCD1602, LCD2004, and LCD12864 are fabricated using liquid crystal materials and communicated using the I2C bus. - It is a high-performance serial bus with bus rules and high-speed or low-speed device synchronization required for multi-master systems. The I2C bus has only two bidirectional signal lines, a serial data line (SDA) and a serial clock line (SCL). - Compatible with all devices with I2C interfaces, such as Arduino, raspberry pi, beagle bone black, tinker board, stm32, esp32 and more. - Package Includes:1 x LCD2004,1 x Jumpwire ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QLRD3TM | | Additional Features | I2C Serial Bus & High Speed Communication | | Aspect Ratio | 16:9 | | Best Sellers Rank | #3,257 in Computer Monitors #3,584 in Single Board Computers (Computers & Accessories) | | Brand | GeeekPi | | Color | Blue | | Compatible Devices | Raspberry Pi, banana Pi, Tinker Board, STM32, ESP32 | | Connectivity Technology | I2C | | Customer Reviews | 4.5 out of 5 stars 140 Reviews | | Display Resolution Maximum | 20x4 | | Display Technology | LCD | | Display Type | LCD | | Has Color Screen | Yes | | Manufacturer | GeeekPi | | Model Name | DFR0154 | | Model Number | DFR0154 | | Native Resolution | 1920x1080 | | Pixel Pitch | 0.6 | | Processor Count | 1 | | Resolution | 400 pixels | | Screen Finish | Glossy | | Screen Size | 20 Inches | | Screen Surface Description | Glossy | | Shape | rectangular prism | | Specific Uses For Product | Business, Education, Gaming, Photo Editing, Programming, Video Editing | | Total Number of HDMI Ports | 1 | | UPC | 703501205959 | | Viewing Angle | 160 Degrees | | Voltage | 5 Volts | | Warranty Description | 6 months | | Warranty Type | Limited Warranty | ## Product Details - **Brand:** GeeekPi - **Screen Size:** 20 Inches - **Resolution:** 400 pixels - **Aspect Ratio:** 16:9 - **Screen Surface Description:** Glossy ## Images ![GeeekPi IIC I2C TWI Serial LCD 2004 20x4 Display Module with I2C Interface Adapter Blue Backlight for Raspberry Pi Arduino STM32 DIY Maker Project BPI Tinker Board Electrical IoT Internet of Things - Image 1](https://m.media-amazon.com/images/I/61zzurKbLML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Just Works *by K***A on February 6, 2025* A good 4x20 LCD with attached I2C controller. Although the picture implies that the controller can be removed, it cannot without unsoldering all the connections to the display itself. Functionally fine, but be aware that I2C LCD controllers are "slow" compared to the standard, multi connection (many wires) method. One may want to try various libraries if refresh speed is an issue. ### ⭐⭐⭐⭐⭐ Use a resistor if screen isn't clear *by D***L on December 21, 2024* I had to buy this for a college project, and the screen worked. At first, the screen was too bright and reading the text was kind of tough, but using a resistor made it crystal clear. ### ⭐⭐⭐⭐ Display Functionality *by A***N on August 31, 2025* Only problem was the lcd itself was moving around internally so the backlight cannot really show what is happening. Would definitely recommend this product though. ## Frequently Bought Together - GeeekPi IIC I2C TWI Serial LCD 2004 20x4 Display Module with I2C Interface Adapter Blue Backlight for Raspberry Pi Arduino STM32 DIY Maker Project BPI Tinker Board Electrical IoT Internet of Things - 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 - ELEGOO MEGA R3 Board ATmega 2560 + USB Cable Compatible with Arduino IDE Projects RoHS Compliant --- ## 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.fr/products/122483689-geeekpi-iic-i2c-twi-serial-lcd-2004-20x4-display-module](https://www.desertcart.fr/products/122483689-geeekpi-iic-i2c-twi-serial-lcd-2004-20x4-display-module) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-06-17*
