Add camera input and a capacitive touchscreen to an RP2350 RedBoard IoT for machine-vision projects. This kit combines the Red Vision Touch Display for RedBoard with the Red Vision Camera Board - HM01B0 (Color), and is designed for quick setup with no soldering required.
The display board plugs directly into the RP2350 RedBoard IoT and carries a 2.0", 320x240px capacitive touch LCD. It also provides Arduino R3 form-factor headers, an I/O expander, and a connector for the included camera board or other compatible 2x9-pin camera boards.
The HM01B0 camera board breaks out the camera module pins to 0.1"-spaced plated through-hole pins and connects to the display board via pre-soldered male headers. It supports live image processing features such as object and contour detection using the SparkFun MicroPython Red Vision Code Package, a MicroPython port of OpenCV.
The hardware is compatible with other 3.3V logic RedBoards or R3 Arduino boards with sufficient processing power, though the Red Vision Code Package is currently supported only on the RP2350. Documentation includes camera and touch display schematics, KiCad files, a hookup guide, MicroPython files, firmware releases and a GitHub repo.

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.
- CLK
- CLK is the clock signal that times when SPI data bits are sent and read. A display needs this pin connected correctly so the controller and screen stay in step while data is transferred.
- 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.
- I2C address
- An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.
- 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.
- 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.
- PTH
- Plated through-hole means the pin holes are metal-lined so solder connects the pad on both sides of the board. It is useful for connectors and headers that need a strong mechanical and electrical connection.
- 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.
