Add a compact visual interface to your RP2350 RedBoard IoT with this Red Vision touch display shield. It plugs into the standard R3 footprint, giving your IoT project a 2.0" capacitive touch LCD without needing external display cabling.
The board is designed to stack neatly with the SparkFun Red Vision Camera Board via its dedicated mating connector, creating a tidy, wire-free machine vision assembly on top of your microcontroller.
An onboard I/O expander lets the display, and the camera’s extra pins if connected, be controlled over I2C. Hardware compatibility extends to other 3.3V logic RedBoards or R3 Arduino boards with sufficient processing power, while the Red Vision Code Package is currently supported only on the RP2350.
When paired with the RP2350 RedBoard IoT, it works with the SparkFun Red Vision MicroPython package, a MicroPython port of OpenCV for tasks such as object detection, colour tracking and contour analysis. Documentation provided by SparkFun includes schematic, KiCad files, hookup guide, MicroPython files, Red Vision MicroPython Package, SparkFun MicroPython OpenCV, SparkFun MicroPython Firmware Releases and GitHub repository resources.

Jargon buster
Plain-language definitions for the technical terms used above.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- I/O expander
- An I/O expander is a chip that provides extra input and output pins controlled through a bus such as I2C. It matters when a board has many display signals, because it helps manage buttons, resets, or control lines without using up scarce microcontroller pins.
- 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.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- 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.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- RP2350
- A microcontroller chip from Raspberry Pi used as the main processor on some development boards. Knowing the board is built around an RP2350 helps you check software support, pin capabilities and whether it suits MicroPython projects.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
