Work and home situation kept me away from having any ham time. But recently I
had some time to continue with upgrading my LE005 transponder design with a
connector (or is it PCI-104 ?), and some other features ;-)
The PC104 is a good choice for having a standarized inter connection system on
CubeSat projects. However, I seen some deviation in the placement standard of
this PC104 connector.
>From the following website I read:
"The CubeSat Kit Bus utilizes the same physical connectors as the
PC/104 bus, but in an alternate physical location so as to avoid unintentional
damage to PC/104 or CubeSat Kit modules."
With my focus on: "...in an alternate physical location..."
I would like to know what this possition is, and if this is now "the golden
in CubeSat world ?
My next worry will be the pin configurations. Is there any standard for CubeSat
Next I would like to know how modules are controlled by the data bus.
Is it like separate pins for PTT, TX, RX etc...
Or with more smart communication with lines like: address bus, data bus, Clock,
Interrupt lines etc. (similar to old ISA PC cards)
Or maybe with I2C.
I keep it to these questions for now...
Next questions will follow out of the answers hihi...
