Here are some pictures of mUnits prototype development process. I have no good camera at the moment so the pictures are a bit unfocused. I’ll make a new set with a good camera as soon as I get one.
The heart and brain: the Discovery Core mUnit based on the powerful STM32F4 Discovery board.
Midi connectivity module with optocoupler to connect MIDI gear.
SD Card module to store data on SD cards.
The spinal cord: the ChipKit Core mUnit with text LCD module for serving sensor data.
The arms: the Circle Control Panel mUnit , 16-sector controller with touch-sensitive LCD display.
The nerves: the parallel-in-serial-out PISO mUnit to convert the signals from up to 128 switch-based sensors (white cables) to simple serial signal (black cable)
The nerves: the serial-in-parallel-out SIPO mUnit to convert serial signals to 8×8 diode matrix signal. One chip can drive up to 64 leds, led lasers etc. to provide visual feedback or send distant control signals to another mUnits. SIPO mUnits can be easily connected in serial to control up to a whole gigantic led display.

The most common command and control bus used on a spacecraft platform is the MIL-STD-1553B covered by the ECSS-E-ST-50-13C. An alternative to the MIL-STD-1553B is the CAN that ESA and the European Space community is standardizing for space applications. UART serial channels are also used especially to control AOCS sensors. The Spacewire technology is now being increasingly used for data transfers < 160 Mbit/s and it can combine the command and control function with massive data transfer.

Isn’t it < 400 Mbit/s now?

Useful information. Lucky me I found your web site by accident, and I am stunned why this twist of fate did not happened in advance! I bookmarked it.
