Frequently Asked Questions

Q: What microcontrollers are compatible with the 0802A LCD Character Display Module?

A: The 0802A LCD module uses the standard HD44780 parallel interface, making it compatible with a wide range of microcontrollers including Arduino (Uno, Nano, Mega), Raspberry Pi (via I2C adapter), PIC, AVR, STM32, and most other common platforms. Standard LiquidCrystal library support makes setup quick and straightforward.

Q: What does "8×2" mean on this LCD display module?

A: "8×2" means the display shows 8 characters per row across 2 rows, giving you a total of 16 character positions on screen. This makes it ideal for compact devices where you need to display short status messages, numeric readouts, or labels without requiring a large screen footprint.

Q: What voltage does the 0802A LCD module operate at?

A: The 0802A LCD character display module operates at 5V DC, which is the standard logic voltage for most Arduino and microcontroller projects. Always ensure your power supply matches the module's requirements for stable operation.

Q: How do I connect the 0802A LCD module to an Arduino?

A: The module features a standard 16-pin header. Connect the data and enable pins to your Arduino's digital I/O pins, wire the power (VCC/GND) to 5V and GND, and use a potentiometer on the contrast pin (VO) to adjust display clarity. The Arduino LiquidCrystal library handles the rest with just a few lines of code.
