Overview:

Scuderia Tor Vergata is the official Formula SAE team for the University of Rome Tor Vergata, based in Rome, Italy. The purpose of the competition is to design and build a formula-style prototype to compete in competitions around the world. This year, the electronics department took on the responsibility of redesigning the dashboard board for the vehicle.

The design of an Testing Device electronic board is a critical process to ensure an efficient "debug" session. The Testing Device must provide an intuitive and easily accessible interface for the operators, allowing them to monitor the board's performance and control its functions.

The Testing Device includes a 20x4 LCD display that provides a clear and sharp display of driving information. It has also a power management system that allows to power up the boards.

Electronic Design:

The board is based on an Arduino microcontroller.

It provides on user panels:

• 6 digital I/O pins, reconfigurable via de Arduino IDE or via MATLAB.
• 4 analog inputs for signals sampling.
• +12V -12V +5V -5V +3.3V bipolar connectors for stable power suppling of the DUT.
• 20x4 LCD display to provide current and power measurements on real time.
• 1 CAN (Controller Area Network) interface.
• 1 Push button with anti-bounce circuit.

PCB design with JLCPCB

JLCPCB (https://jlcpcb.com/) is a company that focuses in prototyping PCBs and SMT assembly. JLCPCB guarantees quality, high precision, and fast board production, which was the primary reason we select ed this company for the PCB production.

JLCPCB's website (https://jlcpcb.com/) offers a service that allows users to upload the Gerber file required for manufacturing, after which, there are numerous configurations that can be managed to meet the needs of the user, such as layers, delivery format, pcb color, and so on.

One of their standout features is that users can include a pcb stencil in their order and configure it on the website (https://jlcpcb.com/).

Thanks to JLCPCB who made the PCBs for us: they also provide us a stencil for SMT device that help us to solder
