Cstick Platform

What defines the Cstick Platform?

Any Screen technology and a revolutionary form-factor enabling a wide range of new use cases.

With the ability to go anywhere and make any computer, or indeed any screen, a thin client for your personal computer, and a secure access point to the cloud, the possibilities are virtually endless.


Cstick utilizes the best in high-end multi-core embedded CPUs in order to provide the heavy lifting required by PC-class applications and compatibility with an enormous software ecosystem.


Market-leading GPU technology for acceleration of anything from advanced User Interfaces to console-class gaming and real-time digital signage, all in HD resolutions.

Media processing

Acceleration of both legacy and cutting-edge media formats, equally suited for web browsing and premium content distribution.


High-speed internet connectivity and standard interfaces for display, power and communication are a crucial part of the ability to be anywhere and connect to anything at any time.


Cstick software stack is built on widely supported OS distributions and FXI provide both binary and source releases in order to let developers customize the platform according to their specific needs.

Any Screen IP

Other micro and minicomputers claim to bring smart technology to “dumb” screens, but the FXI Cstick: Cotton Candy is the only product designed to work with HDMI and USB interfaces.

Translation, FXI’s patented solutions allow for connecting and interfacing with the Cstick compute platform through standard file storage protocols from ANY SCREEN – including Mac, Linux or Windows laptops, monitors and TVs.

Run Android on your Mac or Linux on your Windows laptop, while maintaining the integrity of the content on each device.

No matter what screen a Cotton Candy visits, it delivers a uniform, secure and completely private computing experience.

How it Works

There is complete separation between Cstick and whatever host environment and OS / computer it is connected to.

The host computer simply becomes a thin client for Cstick making it perfect for virtualization of work and private computer environments, bring-your-own-device scenarios, and as a key or “gatekeeper” for secure cloud access.

Through the FXI Any Screen IP™, Cstick is able to utilize any resources present in the host, such as keyboards, mice/touchpads, display and audio output, and even the networking capabilities of the host computer if desired. Interact directly with Android on the device to debug apps, play games and more.

No custom drivers are required meaning that no additional software installation or administrator access is required in order to connect a Windows / OSX / Linux computer to Cstick.

Any computer or other electronic device that supports file system access to removable storage can utilize the FXI Any Screen technology found in the Cstick platform.

For Android

The hardware capabilities of Cotton Candy enable it to run a wide variety of different operating systems for different purposes and preferences.

A single device can switch between different operating systems simply by switching between different microSD cards.

FXI provides official releases of Android ICS and Ubuntu Linux for Cotton Candy, both in binary and source form, with the source code releases forming the basis for anyone wanting to port new OSes to the platform.


The Android code base for Cotton Candy is built on a 3.4 Linux kernel and based on the widely support Android ICS releases from Linaro.

For Linux


The standard Linux code base for Cotton Candy is built on a 3.4 kernel and based on the widely support ARM Ubuntu releases from Linaro.
