The Smart AI Lens kit for micro:bit brings machine vision and AI capabilities to your classroom or maker project. Powered by a K210 processor, the AI Lens camera module can recognise faces, track objects and colours, identify pattern cards, and even learn to recognise custom objects with a single button press.

Designed for use with the ElecFreaks Planet X series, the lens connects via an RJ11 cable over I²C for simple plug-and-play setup. Program it using MakeCode blocks or MicroPython to build interactive AI projects without any cloud dependency — all processing happens on-device.

Key Features

  • K210 AI Processor – On-device machine vision with no cloud connection required
  • Face Recognition – Detect and track faces in real time
  • Object Tracking – Track balls, colours, and moving objects
  • Card Recognition – Identify colour and pattern cards
  • One-Button Learning – Train custom object recognition on the fly
  • RJ11 Connection – Plug-and-play via I²C with Planet X breakout boards
  • Compact Design – Approximately 24 × 36 mm
  • 3.3V Operation – Powered directly from the micro:bit ecosystem
Tip: If your breakout board doesn't have an RJ11 port, you can connect via Dupont wires: Black → GND, Red → VCC, Green → P19 (SCL), Yellow → P20 (SDA).

Ideal For

  • AI and machine learning education
  • STEM classroom projects with micro:bit
  • Interactive robotics and smart devices
  • Computer vision experiments and prototyping

Resources

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.
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.
