Roll Hoop Board: common questions
What microcontroller does the Roll Hoop Board use?
The Roll Hoop Board is built around the PBQ79600PWQ1, from the STM32 family.
How big is the Roll Hoop Board?
The Roll Hoop Board measures 106.7 × 36 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Roll Hoop Board?
26 components, from 22 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 Roll Hoop Board design files?
From the SCFormulaElectric/USC-Electrical-Systems repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Roll Hoop Board design in my own project?
The repository has no license, so all rights stay with SCFormulaElectric. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Roll Hoop Board 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.
