1602 serial lcd module raspberry pi in stock

The principle of the LCD1602 liquid crystal display is to use the physical characteristics of the liquid crystal to control the display area by voltage, that is, the graphic can be displayed.

I2C uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL),pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems with other voltages are permitted. It can be operated as long as it supports the I2C development board.

Features: Easy to use; Less I/O ports are occupied; Support IIC Protocol; The I2C LCD1602 library is easy to get; With a potentiometer used to adjust backlight and contrast; Blue backlight; Power supply: 5v; I2C address is: 0x27.

How to connect it to Raspberry Pi and Ar-duino Compatibility Used for connecting Ar-duino and Raspberry pi and it can be used to display real time clock, temperature, humidity etc.

You can display the digital information or English sentense on the LCD screen by using Arduino, Raspberry Pi or other MCU which supports i2c protocol.

goods as described, fast dispatch. LCD display for use with Arduino. Purchased two, tested before use and found to be 100% apart from the one that I stupidly connected with reversed power connections! Yes! I broke it, so ordered a replacement. The PCB has screen printed connection information but some how l managed to mess this up. The displays appear well made and have a clear lcd with a decent viewing angle. Back light is also good.

Everyone loves the 1602 character LCD, is cheap and works out of box! But the need for 6 to 10 GPIOs is the pain :) It takes most of GPIO of Arduino and other microcontroller. Now with this I2C or Two wires interface LCD, you will save a lot of GPIO for your sensor and motor control.

This is a great blue backlight LCD display. As the pin resources of Arduino controller is limited, your project may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already have I2C devices in your project, you can still program this LCD with the correct I2C address. It is fantastic for Arduino based project.

I am currently having an issue with trying to connect my pi pico with the I2c adapter (LCM1602 of my 1602LCD display. I tried the official example from the raspberry pi github page (It is using the c/++ SDK for pi pico, but this was unsuccessful. I can compile/load the code, but nothing is displayed. I did a I2c bus scan and found out that the I2c address is indeed 0x27. So I know the pins and address are correct. I cant find a good datasheet that gives a overview of all commands for my type of adapter. They also do this weird thing in the code where the send a one byte command in six bytes ( void lcd_send_byte(uint8_t val, int mode) ). I am not very familiar with serial communication, so I dont know if this is normal. Can anybody maybe link a good reference datasheet for a LCM1602 I2c adapter or suggest what the best thing to do is from here?
