Turn your Boffin 300 into a BOFFIN 500 and unlock more experiments. The expansion set brings new parts and projects that develop logic, technical skills, and creativity. Everything works via easy snap-on components onto the board, so building is fast, safe, and fun.

In the manual (download at boffin.cz/support) you will find step-by-step instructions describing what each project should do and how to verify everything works correctly. The set is fully compatible with other BOFFIN kits—so you can combine components and invent your own projects beyond the official guides.

• 200 new projects—FM radio, playback, telegraph, voice- and touch-controlled music, birdsong, police car and ambulance sounds, and more.
• Easy construction—components simply snap onto the base board.
• Educational fun—develop logical thinking, electronics, and experimentation.
• Compatibility—combine with other BOFFIN sets and create hundreds of your own experiments.
• Downloadable manual—complete instructions available online.
