A mobile sensing station is aimed to be released to the market to various engineers. Leading up to this, three separate groups are each responsible for the design choices. This report shall expound on the design choices contributing to the power supply module along with the complete hardware structure. These design choices are bound to a program of requirements based on the group's final goal.

The design choices were justified through rudimentary circuit theory, mechanics and trigonometry. Programming of these design choices were done using C in adherence to using the ESP32-C3 chip. Theories such as numerical methods come into light briefly. Limitations were found to the design choices such as the prohibition to use Li-ion batteries due to safety precautions, which affected the design choices significantly.

We have assembled and tested the power supply PCB, added temperature sensing capabilities, taken various measurements (voltage, current, temperature and SoC) and integrated code with other subgroups. For the hardware, we have made made an enclosure for all the electronics along with a drivetrain system, mostly using 3D printing technology. A first full system integration was not realized at the time of this report. The results show that we have sufficed most of the points in the program of requirements for both the power supply and hardware design. In the end a driving demo version has been reliased. Because of this, a fully functional system integration has been left at a future implementation.
