The pins on the long edge of the board align with those on the 1602 display, straight across. The four pins on one end are labeled, one each for power and ground and two for the I2C connections to the Arduino. The jumper at the opposite end enables/disables the backlight LED **Q: I prefer writing my own device drivers (i work in c / asm). where can i get the datasheet pdf for this device?** A: I would send that request directly to HiLetgo. They have been very helpful to me in the past. **Q: Are the headers pre-soldered?** A: Yes, short male header pins. They go through the LCD PCB and just clear the back of the LCD screen. Clip off header pins flush after soldering. IF you need to remove the original pins, heat the short header pin stub and slide out as the solder becomes liquid. The header black base will melt away. Solder-wick the remaining holes. **Q: How do I obtain the schematic and datasheet for this product?** A: I have not been able to find one. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Funciona perfectamente *by on Reviewed in the United States November 30, 2025* Excelente producto ### ⭐⭐⭐⭐⭐ Works for me on a 1601 LCD *by on Reviewed in the United States August 20, 2025* Not super easy to get setup on Arduino Uno but its working great. I learned the length of hookup wires make a difference. Longer wires (1 foot or so) caused ghosted letters on the display. Here are the critical lines of code: #include #include // include i/o class headerhd44780_I2Cexp lcd; ### ⭐⭐⭐⭐⭐ Works well right out of the package *by on Reviewed in the United States February 19, 2023* After previously purchasing a 20x4 I2C character LCD - also from Hiletgo - I wanted to dive deeper into the world of I2C communications, and I thought that this would be a great companion to the 16x2 character LCD that was included with my Elegoo Arduino UNO starter kit. I had a little bit of trouble with adding solder to the jumpers that assign an address to the modules, mainly because my soldering iron tip was too big, but I eventually was able to set the modules to the addresses that I wanted; I set one to 0x26 and the other to 0x25 to avoid conflicts with the 20x4 display, which I left at the default 0x27 address.Once the custom addresses were set, I proceeded to test the modules using the I2C scanning sketch for Arduino, and they both showed up with the addresses that I wanted. After adjusting the contrast, I wrote up a quick sketch to do some further testing, and both modules did their job and did it quite well. I removed the jumper for the backlight and replaced the jumper with a potentiometer for easy brightness adjustment. ## Frequently Bought Together - HiLetgo 2pcs 5V 2004 1602 LCD Display IIC I2C Adapter IIC Serial Interface Adapter for Arduino Robort Parts - HiLetgo 2pcs HD44780 1602 LCD Display Module DC 5V 16x2 Character LCM Blue Blacklight New - EDGELEC 120pcs Breadboard Jumper Wires 10cm 15cm 20cm 30cm 40cm 50 cm 100cm Wire Length Optional Dupont Cable Assorted Kit Male to Female Male to Male Female to Female Multicolored Ribbon Cables --- ## 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.pe/products/20127321-hiletgo-2pcs-5v-2004-1602-lcd-display-iic-i2c-adapter](https://www.desertcart.pe/products/20127321-hiletgo-2pcs-5v-2004-1602-lcd-display-iic-i2c-adapter) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-10-17*
