The Adafruit TSC2007 is an I2C resistive touch screen controller that offloads touch reading from your microcontroller. Instead of using multiple analog pins and constant polling, the TSC2007 handles all the touch sensing over a simple I2C connection and provides an interrupt pin that signals when a touch is detected.

The breakout board includes a 3V voltage regulator and level shifting for compatibility with both 3.3V and 5V logic. An onboard 1mm pitch FPC connector accepts the flex cable from most medium and large resistive touch panels directly. For other touch screens, the four X/Y contacts are broken out on 0.1" pitch pads for hand soldering or wiring.

Key Features

• I2C Touch Controller – Reads X, Y, and Z (pressure) coordinates over I2C, no analog pins required
• Interrupt Pin (IRQ) – Drops low on touch detection to reduce I2C polling; includes a red LED indicator for debugging
• 1mm Pitch FPC Connector – Plug in most 4-wire resistive touch panel flex cables directly
• 0.1" Breakout Pads – Four X/Y contacts for touch panels with non-standard connectors
• 3.3V and 5V Compatible – Onboard voltage regulator and level shifting
• Fast and Precise – Stable readings with less latency than direct analog reading on an Arduino

Ideal For

• Adding touch input to TFT and LCD display projects
• Microcontrollers without analog inputs
• Projects needing interrupt-driven touch detection
• Upgrading from direct analog touch reading for better performance
