@kinoma

• Preserve progress between prototypes

- Application code - I/O libraries - Look & feel

• Saving time allows you to focus on

- Industrial design - Companion app - User testing - Community building

Don’t Re-Engineer; Expand Priorities

- Crowdfunding campaign management - Investor relations - Building a brand

IoT’s Diversity Makes Traditional Software Development Impractical

JavaScript’s Frontier Left to Conquer

@kinoma

We are preaching the religion of JavaScript for embedded and Internet of Things development

• Performance

• Memory

• User scripting

• Familiar syntax

• JavaScript coders build cool stuff fast

JavaScript Makes IoT Development Usable

@kinoma

JavaScript as the Language of IoT

• programmers work faster • produce more reliable code • it’s trivial to connect to the

cloud and other devices • reading and writing JSON

messages is built in

With JavaScript

@kinoma

ES6 contains more than 400 individual changes to:

• make the language more concise

• improve performance

• integrate support for modules

The addition of modules to the language is fundamental to architecting reliable, long running devices, making JavaScript 6th Edition the right foundation for connecting IoT products.

JavaScript 6th Edition for IoT

@kinoma

Popular Frameworks Aren’t IoT Ready• Browser-based solutions: Too heavy for IoT devices

• Node.js: Server solution being shoehorned into the embedded space

• Qt: Designed for desktop, too much of a catch-all of features

• Lua: Less popular than assembly and COBOL, so difficult to find talent and no significant ecosystem

@kinoma

Available as open source since March 2015. Customers benefit from the flexibility and stability that open source offers.

The first application framework optimized for IoT that speaks the language of the web. Code hardware projects using familiar JavaScript.

Kinoma’s implementation of JavaScript 6th Edition is the smallest, the most complete today, and fast.

Kinoma’s IoT Product Design HardwareCustomizable products for prototypers:

• integrate professional-grade hardware

• use the open source KinomaJS application framework with JavaScript 6th Edition for app development

• use the same pro-developer tools, making prototyping efficient across product teams

Both Delicate and Intimidating

• No Wi-Fi • No case • No battery • No screen • No onboard apps

Why Kinoma Hardware has a Case

@kinoma

Assembling your Raspberry Pi enclosure is relatively straightforward if you’ve ever built any t-slot based laser cut stuff before, but here’s a full guide… - Built to Spec

Introducing Kinoma Element

@kinoma

Introducing Kinoma HD

• Bring most any sensor

• Connect to most any cloud

• Use most any protocol

• Open for developers to expand • PCB designs • 3D design files for case • KinomaJS software • All on GitHub with permissive

open source licenses

Open sensor. Open cloud. Open to expand.
