AAUSAT3 - Hardware

AAUSAT3 PCB.

In AAUSAT3 three type of miccontrollers are used:

• AT90CAN128 at 8/12 MHz
  • running FreeRTOS realtime kernel
  • Two external flash storage chips with our own developed flash storage
  • used for COM, AIS1, EPS, ADCS-1,COM
• ARM7 microcontroller at 60Mhz
  • runningFreeRTOS realtime kernel
  • used for ADCS-2
• BlackFinn DSP for SDR radio
  • running linux
  • used for AIS2

All interconnected with a 500 kbit/sec CANBUS and CSP (Cubesat Space pPotocol)
