Over 40 satellites were launched into extreme low earth orbit by the second stage of the Antares rocket lifting off from Wallops Island, Virginia, USA, on its way to the International Space Station. Each satellite had 8 xChips on board from XinaBox. These xChips were interconnected with XinaBox standard connector and prior to launch qualified for space via rigorous tests, including thermo-cycling, vibration and shock testing.
The xChips onboard is the widely used CC03, an ARM Cortex-M0 32-bit MCU running 48 MHz. It's extreme low-power operation makes it ideal for use in space with only limited solar power availability. The xChip core also incorporates XinaBox' own boot loader allowing the students to simply drag and drop the software to the core, similar to moving a files to a USB Thumb drive.
The other xChips were sensors, which has already been used by students in the classroom, with low-altitude ballooning projects and with proper high altitude (>30km/100000ft) weather balloons. The sensors were:
Ambient light, UVA, UVB and UV Index.
Accelerometer, magnetometer, and gyroscope in X,Y,Z vectors, plus roll and pitch.
5 x satellite frame temperature sensors, measuring the decay temperature as the satellites burned up in the atmosphere.
Infrared temperature sensor allowing the satellites to "see" the earth and the sun.
All satellites in communication successfully transmitted data from all xChips.
