This page documents features from more engineering point of view. For a more user-centric point of view, see Features.
Major Balthazar parts are:
Power Controller and battery
These supply power to the rest of the system, particularly the System on a Module, USB Hub and Display subsytem. It also manages battery.
It should be capable enough to run some USB connected hardware.
See more: Power Supply
System on a Module (SoM)
This is the main system board, the computer. Boards from different makers should be supported.
Minimum of ports is required for wider compaitibility. These are: Power, USB and HDMI.
See more: System on a Module
I/O USB hub
IO-board basically means connectivity with peripheral devices. These can be seen as on-board and out-board. On-board devices include: keyboard + trackpad, webcam and optional audio-card. USB is the usual solution for this.
For more see our I/O USB page.
Display Controller and a screen panel

Case
Initial casing is meant to be made of a recyclable vegetable oil based plastic. Also the idea of a modular design gave us even more sustainable materials to look at - pressed used clothes in resin, cans recycled pressed aluminium and even resin-ed wood saw.
Here are elements we have been working with so far and slowly shaping the final design and a certain materials together.

Software
Software depends on a System on a Module used.
