The SparkFun LCD-09052 is a 16x2 character LCD display module that operates at 3.3V. It uses the common ST7066/HD44780 parallel interface, which means that interface code is widely available for many different controllers and systems.

The LCD-09052 has a white on black display with a white LED backlight. The viewing area is 64.5mm x 16.4mm, and the overall dimensions of the module are 80.0mm x 36.0mm x 8.6mm.

To interface the LCD-09052 to a microcontroller, you will need to connect the following pins:

• Vcc: 3.3V
• Ground: Ground
• EN: Enable signal
• RS: Register select signal
• D4-D7: Data pins

You will also need to connect a contrast resistor to the VO pin. The value of the contrast resistor will depend on the desired contrast of the display.

Once the LCD-09052 is interfaced to a microcontroller, you can use the HD44780 command set to control the display. This command set allows you to write text to the display, clear the display, move the cursor, and perform other operations.

The LCD-09052 is a versatile and easy-to-use LCD display module. It is perfect for a wide variety of projects, such as:

• Digital clocks and thermometers
• Calculators and other simple devices
• Control panels for robots and other machines
• Menu systems for embedded devices

Here are some additional details about the LCD-09052:

• Character size: 5x8 dots
• Viewing angle: 60 degrees
• Operating temperature: -20 to 70 degrees Celsius
• Storage temperature: -30 to 80 degrees Celsius
• Power consumption: <1mA without backlight, <10mA with backlight

The LCD-09052 comes with a header connector that is already soldered to the module. This makes it easy to connect the module to a breadboard or perfboard.

SparkFun also provides a number of resources to help you get started with the LCD-09052, including a tutorial, a hookup guide, and a library for Arduino.

Overall, the LCD-09052 is a great choice for a 16x2 character LCD display module. It is easy to use, versatile, and affordable.
