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.
