## Questions & Answers

**Q: Is the LCD and i2c pre-soldered?**
A: This assembly is completely assembled  and  ready to used with the I2C interface

**Q: What library should you use for python on a Raspberry Pi and where can we download said library?**
A: You use the smbus (import smbus} The Internet will show how to get this.  Here's a start for your code (much reading to do online to show something on the display, including the necessary voltage level transformation circuit for going from the 3.3 volt R-pi to the 5 volt display):

# Interface Raspberry Pi to 16x2 i2c lcd display
import RPi.GPIO as GPIO
import sys
import smbus
import time

# lcd address (verfiy using Linux command sudo i2cdetect -y 1)
addr  = 0x27

#Open i2c from smbus
bus = smbus.SMBus(1)

#much additional code needed, but  there are numerous Internet resources

**Q: Will this work with the arduino?**
A: Yes this works  well with Arduino using the I2C library.

**Q: What are this display's physical dimensions?**
A: Assuming the dimensions haven't changed...
In inches.
The board is 3 & 1/8  x  1 & 3/8
The display bezel is 2 & 3/4   x  15/16
Active display area is 2 & 1/2  x 9/16

## Customer Reviews

### ⭐⭐⭐⭐⭐ Make sure you adjust the small potentiometer in the back until you start to see the number segments
*by M***R on January 12, 2024*

At first I thought these were defective until somewhere on a YouTube sight I heard that the potentiometer in the back-side of the CCA needs to be adjusted for contrast. After I did that, the display came alive. It is nice and bright and works well on its I2C interface.

### ⭐⭐⭐⭐⭐ Excellent Value, No Directions
*by G***N on May 26, 2019*

These LCDs are an excellent value, and both of mine worked perfectly, but they come with no directions. Thanks to the 8574 interface board on the back, you only need 4 connections to an Arduino Uno board, one 5V, one GND, A4 to SDA and A5 to SDL. You’ll also need a zip file with the library for the Liquid Crystal PFC8574 interface. One other thing that should be mentioned is that you need to connect a 2-pin jumper at the pins marked LED on the 8574 board. Two of these jumpers come in the package with the 2 LCDs, but they are not installed – be careful opening the package, because they are tiny and easily lost if they fall out.

### ⭐⭐⭐⭐ Good value, quality could be better
*by V***Y on March 16, 2023*

These work well and are as described. Contrast had to be adjusted via the trimpot at the back. The backlight is bright. There doesn't seem to be any way to control brightness in software, can just turn it on or off. The backlight is required though. Nothing is visible without it. Both units worked fine. Quality could have been better with a little attention to how these are assembled. Looks like they were put together in a hurry.
