Sjc: common questions

What microcontroller does the Sjc use?

The Sjc is built around the STM32F446RET6, from the STM32 family.

How big is the Sjc PCB?

The Sjc measures 160 × 115 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Sjc?

323 components, from 81 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 Sjc design files?

From the tgiacomellibr/sjc 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 Sjc design in my own project?

Yes, under the terms of its MIT license, which tgiacomellibr chose for the repository.

Can I test firmware for the Sjc 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.
