In summary, (you still need to read the whole thing), these boards are for Paradigm, and Paradigm only. It is shared with the world for the benefit of observers and potential Paradigm team members. If you wish to utilize these designs in any way, you must contact us first and receive written permission to utilize the designs for the purpose you require.

We don't want to be restrictive, and we will almost certainly grant you permission, but we want to know what you are using our designs for, and we want to make sure you are using them correctly and safely.

BigSur: common questions

What microcontroller does the BigSur use?

The BigSur is built around the STM32F303R6TX, from the STM32 family.

How big is the BigSur PCB?

The BigSur measures 196.4 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BigSur?

145 components, from 47 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the BigSur design files?

From the ParadigmHyperloop/comp5-electrical repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the BigSur design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the BigSur without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
