Bigger-Brain: common questions

What microcontroller does the Bigger-Brain use?

The Bigger-Brain is built around the STM32H723ZGTx, from the STM32 family.

How big is the Bigger-Brain PCB?

The Bigger-Brain measures 91.2 × 92.3 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Bigger-Brain?

121 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bigger-Brain design files?

From the Nanyang-Venture-Formula/Bigger-Brain repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Bigger-Brain design in my own project?

Yes, under the terms of its GPL-3.0 license, which Nanyang-Venture-Formula chose for the repository.

Can I test firmware for the Bigger-Brain 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.
