From an Electronics Point of View
LiU Formula Student is a student organisation at Linköping University, Sweden. Every year we design and build a formula style race car, which we race with against other universities all over Europe. We started the journey of building an electric car in 2020/21 but were not able to complete it in time for the competitions. Therefore, our main goal for 2021/22 was very straightforward – build an electric car and bring it to an international competition. From an electronics point of view this meant that a lot of new systems had to be designed, built, and tested. The original plan was to design five new PCBs, and do major redesigns of five more. However, as the project proceeded these numbers kept increasing. We wanted to use an iterative approach to the design-build-test cycle, and expected 2-4 versions of each PCB until they were running and had all their desired features. Thus, partnering with a reputable PCB manufacturer such as Eurocircuits helped immensely with the fast production of the many different low quantity orders of PCBs.
The car would feature many different circuit boards. Below follows an explanation of some of them.
