FST Lisboa: 25 Years of Excellence and the First Boards for the FST15<\/strong><\/h3>\n\n\n\n
<\/div><\/div>\n\n\n\n

We are FST Lisboa, a formula student team from Portugal that has been building racing cars for 25 years, having built 14 prototypes, 11 being electric and 5 of those with autonomous capabilities.<\/p>\n\n\n\n

The main goals for this year's prototype is feasibility. However, we still need to think about the future so we want to test self-made inverters and build a new accumulator.<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

The 2024-2025 season is not just another year for it FST Lisboa<\/strong>; it marks a quarter-century of engineering, passion, and racing. As we celebrate ourselves 25th anniversary<\/strong>, the team is hard at work on our newest challenger: the FST15<\/strong>.<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

To kick off the development of our milestone car, we recently received our first batch of PCBs from our long-time partner, Eurocircuits<\/strong>. This delivery included the latest iteration of ours MiniS2C (Sensor-to-CAN)<\/strong> nodes and the DCDC boards<\/strong> for our upcoming accumulator.<\/p>\n\n\n\n

The \u201cAesthetic\u201d Prototype: A Lesson in the Design Process<\/strong><\/h5>\n\n\n\n
<\/div><\/div>\n\n\n\n

Before diving into the specs, every engineer knows that prototyping comes with surprises. In the rush of finalizing the FST15 designs, we made a classic \u201chuman\u201d error: we forgot to include the solder mask layer in the order for these initial boards!<\/p>\n\n\n\n

<\/div><\/div>\n\n\n\n

While they arrived looking like silver-and-copper \u201cnaked\u201d boards, the precision of the Eurocircuits manufacturing remained top-notch. For a prototype phase, these boards are actually a great educational tool\u2014allowing us to see every trace and via clearly as we begin our initial hardware-in-the-loop testing. It's a reminder that even after 25 years, there is always something to learn in the design flow!<\/p>\n\n\n\n

MiniS2C: Engineering for Robustness<\/h5>\n\n\n\n
<\/div><\/div>\n\n\n\n

The MiniS2C<\/strong> is the nervous system of our data acquisition, converting analog sensor signals into CAN messages. For the FST15, we didn't just want it to work; we wanted it to be bulletproof.<\/p>\n\n\n\n
