What makers, students,
and teachers say.

My students actually finish projects now. The tutorials match the hardware exactly, which used to be the biggest blocker.

Hana Okafor
STEM Teacher · Lakeside HS

I went from 'what's a resistor' to shipping a hand-built CO₂ monitor in three weekends. The path just works.

Marco Bianchi
Maker · Milan

The IoT kit is the first one in our maker space that survived a whole semester of undergrads. That alone is worth it.
