My next worry will be the pin configurations. Is there any standard for CubeSat boards ?

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.

Hi William

From my experience you can get a very good start by downloading the data

sheet on one of the EPS modules from Clydespace. Lots of cubesats start by using these power systems and there are many products from other suppliers based on this pinout. The data sheet will tell you which pins are used for which function, but I dont recall seeing a diagram showing the position of the connectors relative to the mounting holes etc.

My effort at a simple cubesat board based on the Clydespace EPS pinout is at: _http://funcube.org.uk/WP3/?page_id=195_ (http://funcube.org.uk/WP3/?page_id=195)

As you can see, there are plenty of free pins !!
