Hardware
The CH-2 uses flash memory for internal storage. It contains no hard disk or other moving parts. The Linux operating system is used for enhanced security and stability. The CH-2 is totally self-contained.

Platform
The CH-2 is designed to automatically adjust to any screen size and orientation. This allows it to be used in browsers on a PC, tablet or mobile phone with no changes or special effort necessary. Supported browsers are Chrome (PC/Android) and Safari (iPhone/iPad). Most other browsers should work, with possible minor visual differences.
