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 compatibility. 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.

Unifying-PCB

Single PCB solution for connecting the three previously designed Balthazar modules (I/O, power supply, USB 2.0, 3.0 controllers, keyboard and adding Compute Module compatible FPGA boards. For more info see our Unifying-PCB page.

Case

Case design is described on a dedicated page.

Keyboard and Touch-pad

For specific Balthazar keyboard, see: Keyboard

We develop add-on PCB to accommodate well known and basically industry standard keyboard as it is found in ThinkPad x2XX series. This will enable users to use an inexpensive replacement keyboard should they have need for it. Casing design envisage accommodating frame to fix additional keyboard in place.

Touchpad on specific Balthazar's keyboard is connected via I2C bus.

Battery

We did implementation and tests with this battery set:

Brand: Samsung

Battery size: 21700

Battery chemistry: Li-ion

Battery: Rechargeable

Voltage 3.6V

Min. capacity in mAh: 4,800.00

Battery version: Flat top

Discharge current: 9.60

Protection circuit: Unprotected

Height: 70.00

Diameter in mm: 21.00


Up to 6 batteries are proposed to power Balthazar, however an additional Battery Control Monitor should be implemented or as a separate unit. Also, research into other battery systems is done.

Current battery candidate implementation and tests. Charging and operating.

  • 5V

  • 12V

Those are battery packs we assembled and into the carrier that fits into the case. In our prototype phase, we implemented those without Battery Charger Monitor. Next stage will be with a BCM PCB.

Software

Software depends on a System on a Module used.
