No complaints at all, but here are a couple of things that might be good to know:1. The LiquidCrystal_I2C library available from within the Arduino app works fine. You don't need any of the variant versions. Just go into the Library Manager and search for LiquidCrystal I2C. The default one by Frank deBrabander works great. The warning "THIS LIBRARY MIGHT NOT BE COMPATIBLE WITH EXISTING SKETCHES" is probably valid, but I had no issues.2. Be sure to check the pin order on the I2C thing. They are labeled. Don't just trust pictures in tutorials.3. The device ID on mine was indeed 0x27. Apparently there is at least one other commonly used value possible, 0x3F. I saw nothing on my display initially, so I tried the I2C scanner on Instructables, which confirmed mine was indeed 0x27. Moral of the story? The potentiometer on the back is very important! Once you're sure your device ID is correct, adjust brightness.Very good deal for what it is - 16x2 characters, nice and bright, and only requires 4 pins (2 of which are power and ground). ### ⭐⭐⭐⭐⭐ Works *by on Reviewed in Canada 16 May 2021* Arrived quickly and well packed.Good display and easy to use ## Frequently Bought Together - GeeekPi 2-Pack I2C 1602 LCD Display Module 16X2 Character Serial Blue Backlight LCD Module for Raspberry Pi Arduino STM32 DIY Maker Project Nanopi 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 - Arduino Uno REV3 [A000066] – ATmega328P Microcontroller, 16MHz, 14 Digital I/O Pins, 6 Analog Inputs, 32KB Flash, USB Connectivity, Compatible with Arduino IDE for DIY Projects and Prototyping --- ## 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.co.th/products/355333900-i2c-1602-lcd-display-16x2-character-serial-blue-backlight-module](https://www.desertcart.co.th/products/355333900-i2c-1602-lcd-display-16x2-character-serial-blue-backlight-module) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-08-27*
