RGB LCD Shield Kit w/ 16x2 Character Display - Only 2 pins used! — Adafruit — 716

This new Adafruit shield makes it easy to use a 16x2 Character LCD. We really like the RGB LCDs we stock in the shop both the RGB negative and RGB positive.

Pinout

  • 5V

    Shield 5 V supply pin for detached use; source says power the 5V pin with 5V.

    Type · powerVoltage · 5V
  • GND

    Common ground for the shield when used detached from an Arduino.

    Type · groundVoltage · 0V
  • SCL

    I2C clock; guide says connect the SCL labelled pin to I2C clock. Also maps to A5 on Uno, D21 on Mega, and D3 on Leonardo.

    Type · signal
  • SDA

    I2C data; guide says connect SDA to I2C data. Also maps to A4 on Uno, D20 on Mega, and D2 on Leonardo.

    Type · signal
  • LCD/keypad via MCP23017

    The MCP23017 I2C port expander drives the 16x2 LCD and UP/DOWN/LEFT/RIGHT/SELECT/RESET buttons, so only the I2C/power pins are needed from the host.

Displays

Character LCDs, SPI TFTs, e-paper modules and larger capacitive-touch TFT panels solve different display jobs. Treat display class, interface, controller, resolution, touch, refresh behaviour, storage, voltage and mounting as separate swap checks.
