qbkit hardware

qbkit edu emulates the mechanical and electrical interfaces of a nanosatellite mission: power and data interfaces, flexible mechanical interfaces and an Open Source computing platform running Linux OS.

The main components of the qbkit edu are:

  • qbkit edu electronics
- Beaglebone Open Source computer.
- qbkit power and data interfaces shield for Beaglebone.
  • 3d printed structure


qbkit edu electronics

Power buses

Qbkit edu electronics contain:

  • Converter 1 and converter 2 step down converters with manually configurable voltage and up to 3A current rating. Factory configuration is the following one:
- Converter 1: 3.3V
- Converter 2: 5V
  • Converter 3: step up converter with manually configurable voltage. Range: from Vin (12V with adaptor supplied) to 28V. Current rating is limited by the qbkit edu power supply (12V at 2A max).

Each power bus contains a current sensor.

qbkit edu electronics contains another step down converter currently not being used.
