The access gap
We mail the lab straight to the kid
Whether a kid gets to try engineering usually depends on their school having a lab, a robotics club, or a budget. Most don't.
Circuit Sprout closes that gap the direct way: free, grade-tailored kits with real tools — micro:bits, Arduinos, Raspberry Pis — plus guided projects and a facilitator guide written so any family can learn together, no STEM background required.
What's in every box
Real tools, not toys
Every kit ships with genuine hardware and everything a family needs to start building together.
- 6 activity cards (one per project)
- A guide written for parents who have never touched a circuit
- Student journal for notes and reflections
- 10 career cards about STEM professionals from underserved backgrounds
- Circuit Sprout sticker sheet
- QR code linking to our online community (Slack/Discord)
- Everything packed in a branded blue-and-white box
