PC104 Pin Distribution
The figure below shows the PC104 connector of FloripaSat-I. The pins are defined as internal (bottom pin cluster) or external (upper pin cluster).
The table bellow describes the standard name of the pins we utilize in the context of the whole satellite. The description for each name is shown below the table.
