Particle has a cool makerspace empowerment program that supplies kits to makerspaces, free of charge, to tinker with their platform. I really like some of the things this company does (including this cool Particle for Good program). From their website:
The Particle Makerspace Empowerment Program supplies local Makerspaces with hardware, special discounts, and dedicated support, all free of charge.
If accepted, your Makerspace will receive a package of free Particle hardware in the mail including:
Two Particle Photon Maker Kits
Four Particle Photon Kits
A unique Particle discount promo code
