## Questions & Answers

**Q: Anyone have a link to the Data Sheet or maybe just a pinout diagram?**
A: I'm not aware of an available data sheet.

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

### ⭐⭐⭐⭐⭐ Cool
*by R***O on June 14, 2025*

Needed it for a class project and worked just nice no probs at all

### ⭐⭐⭐⭐⭐ Works well right out of the package
*by J***S on 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.

### ⭐⭐⭐⭐⭐ A good standard product
*by J***L on January 10, 2024*

I was building an external LCD display to use with my Odroid-C4. I needed an I2C interface. This product provided a reliable circuit board, a pinout description to assure compatibility and easy installation. I just don't like the external power pins for backlight since they are extending beyond the board and don't allow for dynamic controls. I ended up using a 2N7000 with a PWM to control the backlight.
