SparrowHawk: common questions

What microcontroller does the SparrowHawk use?

The SparrowHawk is built around the STM32F722RET6, from the STM32 family.

How big is the SparrowHawk PCB?

The SparrowHawk measures 41 × 41 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the SparrowHawk?

90 components, from 49 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 SparrowHawk design files?

From the benwys/SparrowHawk 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 SparrowHawk design in my own project?

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

Can I test firmware for the SparrowHawk 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.
