CALLIOPE mini 3.0 klassenset basisschool – 20 boards + krokodillenklemmen/LED's

This classroom set equips a whole primary school class with 20 Calliope mini 3.0 boards plus crocodile clips and LEDs, making it the practical choice for introducing coding and electronics to young learners. Unlike single-board kits, it provides everything needed for group projects and hands-on STEM lessons.

Highlights

• 20 Calliope mini 3.0 microcontroller boards
• Includes crocodile clips and LEDs for immediate experimentation
• Built-in 5x5 red LED matrix, RGB LED, speaker, and sensors
• Programmable via MakeCode, Open Roberta Lab, Python, or JavaScript
• Wireless connectivity with Bluetooth 5.1
• USB-C interface for easy connection

In daily use

Teachers can run interactive coding sessions where each pupil works with their own board. The onboard sensors (accelerometer, magnetometer, temperature, light, microphone) and actuators (RGB LED, piezo speaker, motor driver) allow creative projects, from simple light patterns to environmental sensing. The included crocodile clips and LEDs enable quick circuit building without soldering.
