Keyestudio 1602LCD Keypad Shield For Arduino LCD Display ATMEGA2560 For Raspberry Pi UNO Blue Screen Blacklight Module

The Keyestudio 1602LCD Keypad Shield is an easy-to-use expansion board that combines a 16x2 character display and six tactile buttons into a single unit. It is perfect for South African makers, students and hobbyists looking to build interactive user interfaces for their Arduino UNO or Mega projects without messy wiring.

Seamless stacking design

This shield fits directly onto your Keyestudio UNO R3 or compatible control board, eliminating the need for breadboards or jumper wires. It provides a clean, compact setup for prototyping and final projects.

Analogue button input

The shield features five control buttons connected to a single analogue port (A0), saving valuable digital I/O pins for other sensors. Pressing different buttons outputs distinct analogue values, allowing you to easily programme menu navigation.

Clear character display

The built-in 1602 LCD screen displays up to two lines of 16 characters each, featuring crisp white text on a blue background. The active display area measures 20.5mm by 41mm with a character size of 2.95mm by 4.35mm.

Adjustable contrast and backlight

An onboard potentiometer allows you to quickly adjust the backlight and contrast of the display to suit your environment. This ensures optimal readability under different lighting conditions.

Flexible communication modes

The shield supports both 8-bit and 4-bit communication modes with the main control board, defaulting to the efficient 4-bit connection to conserve pins. It operates at an optimum voltage of 5.0V with a low working current of 2.0 mA.

Compact physical dimensions

Measuring 80mm by 58mm by 22mm and weighing just 51.5g, this shield maintains a low profile. It operates reliably within a chip working voltage range of 4.5V to 5.5V.
