Description of πŸ“Ÿ 2Pack GeeekPi LCD 2004 Module with I2C Interface Adapter, Blue Backlight, 20x4 LCD Module Shield for Raspberry Pi and Arduino Uno

The LCD has always been a device that acts as a window in human-computer interaction. For example, the prompt window on some instrument devices, the temperature and humidity prompt box, the device running status monitor, and the prompt screen of the counting device all have LCD figures. The common LCD1602, LCD2004, and LCD12864 are fabricated using liquid crystal materials and communicated using the I2C bus. It is a high-performance serial bus with bus rules and high-speed or low-speed device synchronization required for multi-master systems. The I2C bus has only two bidirectional signal lines, a serial data line (SDA) and a serial clock line (SCL). Compatible with all devices with I2C interfaces, such as Arduino, raspberry pi, beagle bone black, tinker board, stm32, esp32 and more.

Heck, they only have RS232 and no USB to communicate with.

But you can add USB, unsolder RS232 board and solder "1602 LCD USB Mini Drive Board" then it will work with USB. This photo is from testing the NanoPi NEO-LTS USB port with "stress --cpu 4", it showed this on a 4 line LCD. Have a configuration file to display this information on the LCD screen. Gave it 4 stars because it doesn't have a USB port, you need to add a 1602 driver board to it. - Raymond Day

Pros
  • This is a high-performance serial bus with bus rules and high-speed or low-speed device clocks required for multi-master systems. The I2C bus has only two bidirectional signal lines, the serial data line (SDA) and the serial clock line (SCL).
Cons
  • confused

Unlike the device shown in ad

This unit works just like any other 2004 I2C LCD. However, unlike any other device I've used, this one has 2 small metal-framed indentations on each side of the display. Nothing wrong with that. unless you build something with multiple LCDs and add that to the project. It doesn't seem to be the same.

Pros
  • , the LCD has always been a device that served as a window for human interaction with a computer. For example, the prompt window on some instruments, the temperature and humidity prompt window, the instrument operation status monitor, and the counter prompt screen have LCD digits.
Cons
  • Faulty

4 lines, works great with RPi

The display is easy to connect and use with the RPi. The panel is bright and has a brightness control. The Python libraries available made it easy to program the display.

Pros
  • Conventional LCD1602, LCD2004 and LCD12864 are made of liquid crystal materials and communicate via I2C bus.
Cons
  • No paint required
