Prototype Showcase

Bottom side: Main PCB

This main PCB features solar charging with MPPT and efficient boost-buck voltage control. It also contains the 9-axis Inertial Measuement Unit (IMU) and a spectrometer. The main SoC controls the satellite inclusive the payload and connects with the radio (RF) frontend.

Front side: Solar Cell

On this lab-prototype, we used a connectable 6-series triple-junction solar cell. Below the solar cell is the super-capacitor and the inductors, which assure an efficient energy conversion.
