DFRobot Gravity 1602 LCD Keypad Shield for Arduino - 5V, 16x2 LCD, 6-Button Interface
The DFRobot Gravity 1602 LCD Keypad Shield is a plug-and-play interface module designed for Arduino boards, providing a 16×2 character LCD and a 6-button keypad for standalone project control and data display without a PC.
Features
- 16×2 character LCD with adjustable contrast and backlight control.
- Integrated 6-button keypad (Select, Up, Right, Down, Left, Reset) for menu navigation.
- Uses only Arduino pins D4-D10 and A0, leaving most I/O pins free for sensor connections.
- Features DFRobot Gravity 3-pin analog ports for plug-and-play sensor expansion.
- Includes header sockets for direct connection of APC220 or Bluetooth V3 wireless modules.

The DFRobot Gravity 1602 LCD Keypad Shield integrates a standard HD44780-compatible LCD and a Matrix of momentary push buttons into a single Arduino-compatible shield. It operates on a 5V supply and communicates with the host microcontroller via a 4-bit parallel interface, utilizing digital pins D4 through D9. A single analog pin (A0) is used to read the five directional and select buttons via a resistor ladder network.
This shield is engineered for field deployment and debugging of embedded systems, enabling real-time status monitoring and user interaction without serial terminal dependency. The design strategically exposes all unused Arduino I/O pins, including five analog inputs with color-coded Gravity connectors, facilitating rapid prototyping with DFRobot’s sensor ecosystem. An onboard potentiometer allows for LCD contrast adjustment.
