ESPboy is open-source (most software is under MIT license) and open-hardware (CERN license) project.

OSHWA certification record record

ESPboy is a science, technology, engineering, and mathematics [STEM] learning platform which encourages and enhances creativity, imagination, and ingenuity through project-based learning and reverse engineering.

ESPboy is ideal to learn game development, internet of things, start programming, understand how gadgets work, and try robotics basics all with the community help.

It's a fantastic experience to assemble the ESPboy yourself or together with your child. Make your own games and apps, share them with the community online. You can make any fully functional gadget in a minute with additional modules, play with it, understand the way of work, modify it and create the unique new one!

It's about fun engineering education and creativity through limitations :)

ESPboy utilizes a powerful ESP8266 microcontroller with built-in WiFi, Arduino IDE compatible with tons of libs and professional firmware and SDKs
