This interface board is for Red Vision projects where you want the camera and vision stack, but would rather send video to a larger external monitor than use a small onboard screen. With the LCD removed, it acts as a streamlined bridge between a SparkFun Red Vision Camera Board and an RP2350 RedBoard IoT.
The board keeps the RP2350 high-speed pins accessible for other video output options, such as using the SparkFun HSTX-to-DVI Breakout with HDMI- or DVI-compatible monitors. It snaps onto a microcontroller in a standard R3 footprint for a compact, wire-free assembly.
When paired with the RP2350 RedBoard IoT, it supports the SparkFun Red Vision code package: a MicroPython port of OpenCV for object detection, colour tracking and contour analysis directly on the microcontroller. The hardware may also suit other 3.3V logic RedBoards or R3 Arduino boards with enough processing power, but the Red Vision Code Package is currently supported only on the RP2350.
Supporting files include the schematic, KiCad files, hookup guide, MicroPython files, Red Vision MicroPython Package, SparkFun MicroPython OpenCV, firmware releases and GitHub repository.
Features:
- External Display Ready: Ideal for pairing with the SparkFun HSTX-to-DVI Breakout to drive HDMI- or DVI-compatible monitors.
- High-Speed Transmission: Letting you use the RP2350's HSTX pins to output high-resolution video from your object detection and image processing projects.
- Seamless Camera Integration: Provides a dedicated mating connector for the SparkFun Red Vision Camera Board.
- R3 Footprint: Snaps directly onto your microcontroller in a standard R3 footprint for a compact, wire-free assembly.
- Powered by OpenCV: Unlocks the SparkFun Red Vision code package when paired with the RP2350 RedBoard IoT.
Specifications:
- Headers: Male R3 Headers (2x 8 pin, 1x 10 pin, 1x 6 pin)
- Camera connector: 2x10 Socket (for connecting a compatible Camera Board)
- On-board component: I/O Expander
- Power indicator: Power LED (Red)
A practical option for Red Vision builds that need external monitor output for object detection, colour tracking and image processing experiments.
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.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- 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.
- HSTX
- HSTX is a high-speed transmit interface on RP2350-based boards for sending fast digital signals such as video-style data. It matters because it uses carefully routed high-speed signal pairs rather than ordinary low-speed wiring.
- 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.
- 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.
