Adafruit Resistive Touch screen - 3.7" Diagonal

This resistive touch screen is highly versatile, compatible with both stylus and fingertip inputs, making it ideal for microcontroller projects. Its 2.45" x 3" (62mm x 76mm) dimensions and 3.7" diagonal active area provide ample space for interactive interfaces.

The touch screen features a 4-wire resistive display with 600 ohms across the X pins and 300 ohms across the Y pins, housed on a 1.0mm pitch FPC connector. It works seamlessly with any microcontroller using two digital pins and two analog input pins.

Though the connector isn't breadboard-friendly, it pairs perfectly with our touch screen breakout board for straightforward connections. Transform it into a USB touchscreen using our AR1100 USB Mouse adapter, or integrate it with a microcontroller via our STMPE SPI/I2C breakout.

We've developed comprehensive example Arduino library code for direct microcontroller connections. This code illustrates reading inputs, debouncing signals, and measuring touch pressure—essential for fine-grained touch detection. The straightforward code can be easily adapted to other microcontrollers.

To deepen your knowledge of touchscreen functionality and input-reading techniques, consider exploring a helpful application note that complements your hands-on experimentation.
