The document summarizes the CHIRIMEN open source hardware and software project. It describes CHIRIMEN as a single-board computer driven by a web browser, with specifications including a dual-core CPU and other components. The project aims to connect the web and real things by using a browser as the operating system. It released the hardware design and software as open source to promote developing web technologies for embedded systems and IoT devices. The open source code includes designs for manufacturing the board as well as a browser-based OS and APIs to control sensors and actuators from web apps.

1. ＣＨＩＲＩＭＥＮ Open Source!

2. We released CHIRIMEN as an open
source at last at the end of April, 2016.

CHIRIMEN: SINGLE-BOARD COMPUTER DRIVEN BY THE WEB BROWSER
• 1.6GHz Dual Core Cortex A9 CPU
• Mali400 Quad Core GPU
• 1GB DDR3 SDRAM, 8GB NAND Flash
• USB, MicroSD, GPIO, I2C, SPI …
• Boot to Gecko OS (Web browser as OS)

4. CHIRIMEN OPEN HARDWARE PROJECT
•Open community hosted by Mozilla Japan
•Pursuit for the technology which connects Web,
especially the web browser to real things.
•Try open source of not only software but hardware.

5. Why is it a web browser?

6. The issue of Internet of Things
Although network communalization is promoted, apps, services and
things are separated by vertical for every company or alliance.
Internet

7. Web of Things
Realize cooperation by Web as an app service platform of an open standard.
＝ The concept of Web of Things
Web
Internet
This picture is intelligible for a telecom industry.
Almost compatible with ITU-T’s M2M Service layer*1.
However, it is not the whole picture of IoT.

9. Dig down the Web of Things
Decompose the IoT by functionality
Apps, Services
Interfaces to Sensors and
Actuators
Human to Machine Interface
Web
Internet
This side is seen by the IoT reference
architecture model*1 of ISO etc.

10. The issue of Internet of Things
It was divided by the individual computing platform.

It was proposed by TPAC2015. and
added to the WoTIG workspace.
web should also support the world of embedded computor!

In a Web native generation,
this one is already more intimateHMI of a legacy ramp

15. PERVASIVE BROWSERS： REPLACE HARDWARE HMI BY HTML+CSS
• Multi-lingual and multi-modal
• Extensibility and agility

16. CHIRIMEN OPEN SOURCE

22. WHEN DO I GET AN ACTUAL BOARD?
It is under negotiation wholeheartedly!
Release of the hardware design and software in open
source license was important Milestone for it.
Probably, something may be set up by the event of next page 

23. WE EXHIBIT IT AT MAKER FAIRE TOKYO.
Sat., August 6, 2016, Sun., 7th Tokyo Big Sight
IT WAS EXHIBITED ALSO MAKER FAIRE NYC2015.
