Rapid IoT Prototyping

with Canopy

Presented by Greg Prisament (greg@canopy.link),

founder of Canopy.

2014 SFIoT UnConference (8/16/2014)

An end-to-end IoT software platform.

Selling Points

100% open source.

Designed for commercial use.Designed for commercial use.

Creating a cloud-

managed product today

is expensive and

difficult…

Complex software systems are involved.

Most platforms are proprietary and

expensive to license.

… but it doesn’t need to be that way.

What if IoT software were free,

readily-available, and easy-to-use?

Canopy makes it simple to develop

commercially-viable smart products.

Low-latency control from anywhere.

Seriously. Any similarity to an actual product is purely coincidental.

Our Emphasis

Powered Appliances

We assume moderately powerful HW:

• ARM-based SoC

• Internet access over WiFi, ETH0, 3G, or 4G LTE

• Linux-based OS• Linux-based OS

• Websockets & SSL
