Technical Details
Dimensions: The display is designed to accommodate 20 characters horizontally and 4 lines vertically. Each character is typically made up of a 5x8 pixel matrix.Interface: Common interfaces for such displays include parallel interfaces SPLC780D. These interfaces allow microcontrollers or other devices to communicate with the LCD, sending commands and data.
Character Set: These displays often use a standardized character set, such as ASCII (American Standard Code for Information Interchange) or a custom character set defined by the manufacturer.
Backlight: The backlight is often Green or blue.
Voltage Requirements: Common voltage levels include 5V for logic and backlighting.
Contrast Adjustment: This display allows the user to optimize the display's visibility by adjusting the contrast between the characters and the background.
Connection Pins: The display is connected to a microcontroller or other device using a set of pins. These pins include power supply pins (VCC and GND), data pins (D0-D7 for parallel communication), control pins (RS, RW, and EN), and sometimes backlight control pins.
Communication Protocol: The communication between the microcontroller and the LCD is often done using a specific protocol. Parallel interfaces, involve sending commands and data using the specified pins.
Driver IC: The display is driven by an internal controller or driver IC (Integrated Circuit). The SPLC780D is a common controller used in these types of displays.

Customer Reviews
This works great with the i2clibraries.i2c_lcd class in Python. I tried it on 3.3v, but it needs the 5v. The backlight comes with a jumper cap, but I swapped it for a 10k pot, so now I have brightness control as well (see pic). And, its bigger than you expect, especially after using tiny oleds.
Nice bright display. Unfortunately it didn't last- it lost most of the characters. Now it is a 2x8 display.I restored the rating to 5 stars because further investigation showed it was an over voltage condition that damaged the display. Would recommend this product over the other sellers because the serial interface is already soldered in place, so saved a few minutes. Plus, a better price.
Replaced a 16x2 Lcd with this and I love it! Installing and modifications of the arduino code was a breeze. Used the LiquidCystal_I2 library. Example sketch included a scanner for finding the address. (0x27 on mine). If you are using a 16x2 this is a great upgrade!
Works fine. I did not need, nor want the feature of the IIC board, so I removed it and used the display as a parallel type.
As an I2C device this was a no brainer and didn't consume any pins on my Arduino since the I2C bus is shared with several other devices. Once you adjust the potentiometer for the brightness it is very nice to read. It needs a different library than its 16x2 cousin but that was a breeze to find and install.
It’s great I2C, safe a lot of pins with it
No issues with this. Using it with Arduino Uno. Almost plug and play.
Needed to adjust the potentiometer on the back to get it to display but works good for the price.
great buy
The first was defective. The second is great. The I2C address in your program may need to be adjusted
