Compatibility
This module works with any 5V microcontroller that has at least 6 GPIO pins, such as Arduino Uno, Mega, or Nano. For 3.3V systems like Raspberry Pi or ESP8266, use a level shifter or enable 3.3V-compatible mode if supported by the module variant. It pairs well with common sensors and I2C adapters to save pins.
Wiring Notes
For a standard Arduino setup, connect VSS to GND, VDD to 5V, V0 to the middle pin of a 10K potentiometer (with ends to 5V and GND), RS to digital pin 12, EN to pin 11, D4-D7 to pins 5-4-3-2. Tie R/W to GND. In code, use the LiquidCrystal library with 4-bit mode.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno?
Yes, the 16x2 LCD works directly with Arduino Uno using 5V logic and the standard LiquidCrystal library. Connect as per the wiring notes above.
Does it need a potentiometer for contrast?
A 10K potentiometer is recommended to adjust the contrast voltage on pin V0. Without it, the display may show blank or dark boxes.
Can I use this with 3.3V microcontrollers?
This module is designed for 5V operation. To use with 3.3V boards like ESP32 or Raspberry Pi, you may need a level shifter for data lines or select a 3.3V-compatible variant.
