Q7 ACS DaughterBoard

The Q7 Attitude Control System (ACS) daughterboard is a daughterboard for the Q7 processor card that provides a suite of functions and interfaces that are commonly required in a satellite ACS subsystem. Given the large suite of interfaces and functions available on the board, it can also be used in more general applications, where only a subset of the available functions are required.


The Q7 ACS Daughterboard offers the following key features:

  • Numerous RS-422 and RS-485 serial interfaces, multiple GPIO
Additional Functions:
  • Multiple switchable 5V, 15V, and 28V outputs, 3x full H-Bridge drivers, current and voltage monitoring & telemetry
  • 100 x 76 x 14.5 mm (with Q7, excluding RJ45 connector)
Input Voltage:
  • 25 to 34V (28V nominal)
Power consumption:
  • 2.7W @ idle

Specific Use

The Q7 ACS daughterboard, in conjunction with the Q7, is generally used as an Attitude Control System computer or as a satellite platform’s Onboard Computer (OBC). Given the large suite of interfaces and functions available on the board, it can also be used for more general use, connecting to numerous other systems in a bus or payload for command and control applications.
