TBB: common questions

What microcontroller does the TBB use?

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

How big is the TBB PCB?

The TBB measures 139.7 × 63.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the TBB?

159 components, from 76 distinct parts. The full bill of materials is listed on this page.

Where can I download the TBB design files?

From the formulaslug/fs-4-schematics repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the TBB design in my own project?

The repository has no license, so all rights stay with formulaslug. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the TBB 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.
