The contrast is the weakest when connected to the positive power supply. The contrast is the highest when connected to the ground power.When the contrast is too high . The contrast can be adjusted by a 10K potentiometer. RS:for the register selection, Select the data register when the level is high, and select the instruction register when the level is low. R/W :Work as the read-write signal line, read operation when high level, write operation when low level. When RS and RW are low the same time, you can write instructions or display addresses, when RS is low, RW is high, you can read the busy signal, when RS is high, RW is low, you can write data. E: Work as the enable terminal. When the E terminal changes from high level to low level, the LCD module executes the command D0 to D7: 8-bit bidirectional data lines. A:Positive backlight power supply k:Negative backlight powerPackcage Included: 2pcs 1602 16x2 LCD Display Module Review: Easy, Quick, Product works; 1 of the 2 had a speck beneath the screen, seller refunded money asap - SEE BELOW for setup tips: Product is great - one of the two had a black speck underneath the screen, but when I contacted the seller to tell them and ask them how they would like me to proceed, they refunded my money for the entire order - fantastic support! Bummer that I only got one but that's how manufacturing goes sometimes. I will be purchasing more when I need them. - Connected up to Arduino Uno through YT vids and other resources (google will help with these) - Pulled some sketch code from Arduino site - Tested the LCD screen AT FIRST, I didn't realize there was a knob to turn with a screwdriver on the back. That is on the I2C bus (soldered to the LCD screen, and slightly tilted [normal]) and it controls the brightness of the LCD screen. Good luck and have fun! Review: These screens work great. Just make sure you check what chip is on it. Details in my review. - There are 2 types of I2C chips on these "If you have the PCF8574T. the default I2C bus address is 0x27. If you have the PCF8574AT the default I2C bus address is 0x3F." More information here. Google "tutorial-serial-i2c-backpack-for-hd44780compatible-lcd-modules-with-arduino/" If you run the command "i2cdetect -y 1" the output will show you if it is 0x3F or 0x27. I followed this video guide to get this working with my Raspberry Pi Zero. Youtube search "Raspberry Pi - Mini LCD Display Tutorial" by TheRaspberryPiGuy. These screens are great value for money and are really easy to use. ## Features - Display: 2-lines X 16-characters - Fit for Arduino and Raspberry pi - Color: Blue with white character color - Less I/O ports are occupied, only four - VCC, GND, SDA, SCL ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0711WLVP9 | | Additional Features | Portable | | Aspect Ratio | 16:9 | | Brand | LGDehome | | CPU Model | 1.2GHz Cortex A9 Processor | | CPU Model Number | LGDehome-08hg | | CPU Speed | 1 | | Color | Blue | | Connectivity Technology | I2C | | Customer Reviews | 4.3 out of 5 stars 131 Reviews | | Display Resolution Maximum | 16x2 | | Display Type | LCD | | Graphics Card Description | Dedicated | | Graphics Card Interface | Integrated | | Graphics Description | Dedicated | | Hard Disk Description | HDD | | Hard Disk Interface | Solid State | | Human-Interface Input | Buttons | | Manufacturer | LGDehome | | Model Name | HD44780 1602 | | Model Number | LGDehome-08hg | | Native Resolution | 16x2 | | Processor Brand | LGDehome | | Processor Series | 1.2GHz Cortex A9 Processor | | Processor Speed | 1 | | Resolution | 16 x 2 | | UPC | 753610374374 | | Video Output Interface | I2C | ## Product Details - **Brand:** LGDehome - **CPU Model:** 1.2GHz Cortex A9 Processor - **CPU Speed:** 1 - **Graphics Card Description:** Dedicated - **Model Name:** HD44780 1602 - **Color:** Blue - **Special Feature:** Portable - **CPU Manufacturer:** LGDehome - **Connectivity Technology:** I2C - **Display Resolution Maximum:** 16x2 ## Images ![2 Pack HD44780 1602 LCD Display Module DC 5V 16x2 Character Blue Blacklight - Image 1](https://m.media-amazon.com/images/I/51qwOjV7YzL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy, Quick, Product works; 1 of the 2 had a speck beneath the screen, seller refunded money asap *by R***. on February 13, 2019* SEE BELOW for setup tips: Product is great - one of the two had a black speck underneath the screen, but when I contacted the seller to tell them and ask them how they would like me to proceed, they refunded my money for the entire order - fantastic support!

Details in my review. *by D***H on October 19, 2018* There are 2 types of I2C chips on these "If you have the PCF8574T. the default I2C bus address is 0x27.

These screens are great value for money and are really easy to use. ### ⭐⭐⭐⭐ Looks great as long as you have a 5V power source and 5V tolerant board *by J***B on August 2, 2017* This LCD Works Great for 5V Arduino Boards (and maybe some 3.3V boards) NO Instruction were included NO software or demo scripts or links were included in the box Does not work as expected when powered by 3.3V to the LCD (5V is really needed for power) To get it working without instructions required more than an hour of frustration. The default address of this LCD was found to be 0x3F. I was able to find the address by running an I2C scanner script. Once you know the I2C address of the LCD display, you will need a script that is compatible with the chip on this LCD display and then you must enter the I2C address. The only script I could find that worked with this LCD was the LiquidCrystal_I2C library on GitHub and I installed it into my Arduino library. To set the LCD address properly in the Arduino script software, I changed a line of the script to read LiquidCrystal_I2C lcd(0x3F,16,2); The 0x3F is the address, 16 are the characters, and 2 are the number of rows of this LCD display. The second issue was that the LCD the characters do not work properly when run from a 3.3V source. When connected to a 3.3V source, the characters were dark on a dark blue background and not visible except at an extreme angle and with the pot on the back pushed past it's normal range. The work around was to power the LCD Vcc by the USB 5V power and thankfully the I2C pins on my 3.3V Arduino board are 5V tolerant, so the Arduino chip did not burn up. I also had to adjust the potentiometer on the back of the LCD display, to get the contrast right after applying 5V. I photo is attached and it looks good now that it is working and I hope you have a faster success than myself. -J Blaha --- ## 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.pt/products/43527380-2-pack-hd44780-1602-lcd-display-module-dc-5v-16x2](https://www.desertcart.pt/products/43527380-2-pack-hd44780-1602-lcd-display-module-dc-5v-16x2) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-18*
