A Community called "MozOpenHard Project" of Mozilla Factory is developing a powerful B2G (OSS version of Firefox OS) based developer board and WebAPIs for hardware (I2C and GPIO) control. The environment which contain both hardware and sotfware is called CHIRIMEN. It is under development and is not yet ready for purchase for now.
Note: This page will be updated first on Japanese page.
CHIRIMEN is a development environment for controlling physical devices, such as sensors and actuators, that use Web technologies. It is the catch-all term for both the board computer and its software.
