Hello everyone,
We are the Democritus Racing Team (DRT), a student team from the Democritus University of Thrace participating in Formula Student. We are just a group of engineering students learning as we go, trying our best to build an electric race car. Designing our electronics from scratch is a huge challenge for us, but it’s the best way to gain hands-on experience, and we are excited to share our latest project with this community.
Controlbox Data Logger
This custom PCB serves as the central hub for our race car’s data system. Its primary job is to collect critical data from the car’s sensors and the driver’s inputs, safely storing it onboard so our team can analyze the vehicle’s performance after every track session.
At the core of the board is an STM32H7 microcontroller that handles all the data processing. To understand how the car is behaving on the track, the design includes positioning and inertial tracking modules that continuously measure speed, G-forces, acceleration, and handling dynamics.
To store all this information, the board is equipped with an SD card. This allows us to safely log all our telemetry data during a run, which we can then easily extract via a USB interface once the car is back in the pit. Additionally, for communication with the rest of the car, we use a dual CAN bus architecture to interact with all the vehicle’s subsystems.
Finally, we want to give a massive thank you to AISLER for their generous sponsorship and for manufacturing our boards! As a student team, their support, speed, and top-notch quality are incredibly helpful in getting our car on the track. We truly appreciate it!
