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

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- FPC
- FPC stands for flexible printed circuit, a flat flexible cable or connector style often used where space is tight. It matters because this breakout needs the correct pin count and pitch FPC cable to connect reliably to the display or high-speed interface.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- IRQ
- Short for interrupt request, a signal pin a device uses to get a microcontroller’s attention when something needs handling. It matters here because I2C communication with the sensor requires connecting the IRQ pin to a suitable input pin.
- LCD
- LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- TFT
- A thin-film transistor display is a common type of colour LCD used for graphics screens. Knowing a product is for TFTs helps you check that the driver board matches the display’s connector, resolution, backlight, and signalling method.
