Balthazar Modules set
Those are Balthazar's modules and adjoining devices top view. Below is a description of each module.
All PCB modules are to be connected through with the flat and short USB cables to a power supply PCB that also charges the batteries and controls the voltage. As it is shown in a video on our Instruction manual page. Power supply would need an external USB-C charger.
Description of the Balthazar modules
1. Module Balthazar PSU is a combined battery charger, buck-boost converter and stereo power amplifier. It also delivers the power to the whole modular system, also via flat USB cable.
Technical description:
Universal power adapter – 12Vdc/5A (60VA Max) – the most usual laptop power connector / either exterior or inserted into chassis skeleton
Input RFI filter
Buck/ boost converter - 5-15V -> 5.1V (which is VSYS voltage on mainboard)
LiPo battery pack single-cell charger -> from SYS voltage 5.1V
Up to a large LiPo battery pack (10000mAh) – single cells / in parallel = 3.6V – three-terminal connector (-Vbat=gnd, thermistor NTC_TS, +Vbat=3.6V)
Options: charge to/from/use external 5V battery pack (USB-A and/or USB-C connectors), solar panel charger.
VSYS voltage is the main motherboard voltage line – use appropriate buck or boost converters on all separate functional modules (CPU, graphics, ram, etc.)
2. Module Balthazar Keyboard is a simplified, a bit ergonomic computer keyboard with DIY approach. In the two versions. The second iteration of the updated keyboard is to have some more geometric consistency.
3. Module Balthazar IO is a simple USB2.0 four-port hub for the internal devices: keyboard and touchpad (optional trackpad), webcam and optional audio card. This is for an internal connection only and if the user wants to use a variant of some other ARM based systems, such as Raspberry Pi 4, or something compatible. End user will also have to disconnect and take out Unifying board, as that place is envisaged for such additional system.
4. Module Unifying PCB is a 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. Aimed at setting a compatibility standard to widely accepted hardware standards.
