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 board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny 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 connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering 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 adds extra input and output pins controlled through a bus such as I2C or SPI. It can drive buttons, LEDs, relays, resets, or other 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 (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
microcontroller: A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
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.
