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 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.
CLK
CLK is a clock line that times when bits are sent and read on a synchronous serial bus such as SPI. Any device using a clock line must have its CLK connected to the controller's clock output so the two stay in step while data is transferred.
fps
fps means frames per second, or how many video images are captured or displayed each second. A higher fps generally gives smoother motion, which helps when the camera or the scene being viewed is moving.
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.
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.
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 (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.
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.
through-hole
A mounting style where the component leads pass through holes in a circuit board and are soldered on the other side. Through-hole parts are often easier to handle and solder by hand, which is useful for classroom and hobby projects.
