2.8” TFT Resistive Touchscreen for Arduino

Resistive Touchscreen for Arduino: colourful, bright and interactive

The 2.8" Resistive Touchscreen by Adafruit comes in the form of a shield to help you set up your Arduino projects. It has a high-quality display for immediately viewing your data: images, e-mails, text messages and information of a more technical nature are all perfectly legible!

• The shield has a pleasant-sized TFT screen (2.8” diagonal) offering a vast choice of colours with 262,000 shades available in 18-bit mode and a great brightness thanks to a backlight with 4 white LEDs, which can be controlled with a digital pin connection.
• TFT (thin-film transistor) technology is synonymous with rapidity, as it significantly reduces response time while preserving colour definition.
• The resistive screen’s touch option opens up all kinds of interactive possibilities. You can create an authentic keypad for a smartphone or tablet, or develop a program for drawing or playing!
• You can also connect a MicroSD card to store your data. They’ve thought of everything!

A plug-and-play screen for easier integration

You’re no doubt familiar with the shield system: because it’s equipped with all the necessary connectors, already welded to the controller, you can connect your hardware to your programming board in a flash.

In this case, the TFT resistive touchscreen proposed by Adafruit is a true plug-and-play screen; already assembled and tested, it’s ready for use in just 10 minutes after downloading an Arduino code library.

It can be used alone with the Arduino Uno, Duemilanove and Diecimila boards. Mega and Leonardo enthusiasts will need to solder 3 jumpers, but can then reap the full benefits of these two boards.
