Add vision and touch control to the Experiential Robotics Platform (XRP) Kit without soldering. This kit combines a Red Vision Touch Display for Pico with a compatible Himax HM01B0 colour camera board, enabling live image processing along with object and contour detection.
The 2.0" capacitive touch LCD is mounted on a breakout board designed to plug directly into the XRP Control Board as well as Raspberry Pi Picos. The display board also provides a camera-board connector, µSD card connector, Qwiic connector and an I/O expander controlled over I2C.
The camera board breaks out the HM01B0 module to 0.1"-spaced plated through-hole pins and is supplied with headers fitted for connection to the Red Vision Touch Display. It works with the SparkFun MicroPython Red Vision Code package, a MicroPython port of the popular OpenCV image processing library.

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.
- 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.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
