It features adjustable backlight and contrast via a potentiometer, operates on a 5V power supply, and supports easy integration with provided libraries. Ideal for makers 14+, it combines efficiency and reliability, backed by strong user reviews and a 1-year warranty. ## Description Product description Introduction As we all know, though LCD and some other displays greatly enrich the man-machine interaction, they share a common weakness. When they are connected to a controller, multiple IOs will be occupied of the controller which has no so many outer ports. Also it restricts other functions of the controller. Therefore, LCD1602 with an I2C port is developed to solve the problem. It is also simple to handle. It has only two bidirectional data lines, a serial data line and a serial clock one. How to wire: GND—GND; VCC—VCC; SDA—A4; SCL—A5 Application Used to display Characters, letters and Numbers. Component: 1 * I2C LCD1602 With IIC/I2C interface, it only takes two I/O port thus saving more for other usages. You can adjust the contrast by the potentiometer at its back. If you don’t want the backlight, you can also unplug the jumper cap at the LCD back. With the LCD shield, you can display whatever you want by programming the code compatible with Arduino, Raspberry Pi board. Therefore, this is a perfect choice to make your project more interesting and vivid! 1602 I2C Specification Display: 4 lines x 20 characters Backlight: Blue with white character color Pin Definition: VCC/ GND/SDL and SCA Contrast Adjust: Potentiometer Backlight Adjust: Jumper Default Address: 0x27, 0x3F Working Voltage: 5V Package 1 x 1602 lcd display with I2C serial interface Review: Great Product, Great Price, Fast Delivery! - Works great! Thanks Review: Good Display for Projects - Worked perfectly for my esp32 project, shipped quickly, and I have nothing bad to say about the product! ## Features - Easy to use. Less I/O ports are occupied, only four - VCC, GND, SDA (serial data line), SCL (serial clock line). - Support IIC protocol. The I2C LCD1602 library is provided, so you can call it directly. - With a potentiometer used to adjust backlight and contrast. - Power supply: +5V; Address of the module: ox27 - Note: This item is suitable for 14 years and older. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B019K5X53O | | Best Sellers Rank | #314 in Single Board Computers (Computers & Accessories) | | Brand | SunFounder | | Built-In Media | I2C LCD1602 | | CPU Model | 210 | | Compatible Devices | Arduino, Raspberry Pi | | Connectivity Technology | I2C | | Customer Reviews | 4.6 out of 5 stars 476 Reviews | | Item Dimensions L x W x H | 4.9"L x 1.7"W x 0.4"H | | Manufacturer | SunFounder | | Memory Storage Capacity | 1 TB | | Mfr Part Number | TS0351 | | Model Name | 2004 20x4 LCD Module | | Model Number | TS0351 | | Operating System | ios | | Processor Brand | ARM | | Processor Count | 1 | | RAM Memory Installed | 1 MB | | RAM Memory Technology | LPDDR3 | | Ram Memory Installed Size | 1 MB | | Smart Home Compatibility | Not Smart Home Compatible | | UPC | 701715367685 | | Unit Count | 1.0 Count | | Warranty Description | 1 Year Guarantee | | Wireless Compability | 802.11b | ## Product Details - **Brand:** SunFounder - **CPU Model:** 210 - **Memory Storage Capacity:** 1 TB - **Model Name:** 2004 20x4 LCD Module - **Ram Memory Installed Size:** 1 MB ## Images ![SunFounder IIC/I2C/TWI LCD1602 Display Module Compatible with Arduino and Raspberry Pi - Image 1](https://m.media-amazon.com/images/I/71TsnKeXQcL.jpg) ![SunFounder IIC/I2C/TWI LCD1602 Display Module Compatible with Arduino and Raspberry Pi - Image 2](https://m.media-amazon.com/images/I/71-zJXH46QL.jpg) ![SunFounder IIC/I2C/TWI LCD1602 Display Module Compatible with Arduino and Raspberry Pi - Image 3](https://m.media-amazon.com/images/I/71fxohcikKL.jpg) ![SunFounder IIC/I2C/TWI LCD1602 Display Module Compatible with Arduino and Raspberry Pi - Image 4](https://m.media-amazon.com/images/I/712tBP4h49L.jpg) ![SunFounder IIC/I2C/TWI LCD1602 Display Module Compatible with Arduino and Raspberry Pi - Image 5](https://m.media-amazon.com/images/I/7127t5fBssL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: It it possible to change the address of the lcd to have multiple lcd on the same bus?** A: To further expand on Wes' answer (which is excellent!), you can have up to eight (8) on the same bus, per the chip datasheets. The chips have a portion of the address hard-code (which cannot be changed) and the three remaining address lines (A0, A1, and A2) can be jumpered to ground to set seven (7) other addresses - the 8th being no jumpers. IF you happen to get one with an 8574 chip and another with 8574A or 8574T, then you could potentially have up to 16 modules on the same bus as the A and T versions use a different hard-coded address than the 8574. **Q: Has anyone run this display on 3.3 volts successfully? I'd like to use it on an 8266-12E to display the ip address.** A: It works on 3.3V, but just barely: it's unusably dim. I changed the supply voltage to 5V and was able to successfully drive it with 3.3V-level I2C signals, although the PCF8574 data sheet says that the minimum Vih level is 0.7 * Vcc = 3.5V. My scope says that the signals are rising to about 3.8V, so there must be some kind of pull-up to 5V on the I2C backpack board. I don't want to rely on that, so for my final design I'll use a PCA9306 I2C level shifter. **Q: Do these come with an I2C backpack? I just ordered some of these and they came with no backpack in the package.** A: There are several product options on the page, some have I2C, some don't. If you chose one that has I2C, it should come with an I2C backpack. **Q: Does this work for the old raspberry pis that have a 26 pin gpio?** A: This module uses an i2c serial interface rather than discrete gpio pins. If your rpi has an i2c, it should work. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Product, Great Price, Fast Delivery! *by A***N on November 23, 2024* Works great!
