Hexdump: common questions

What microcontroller does the Hexdump use?

The Hexdump is built around the STM32F030F4, from the STM32 family.

How big is the Hexdump PCB?

The Hexdump measures 25 × 447 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Hexdump?

71 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hexdump design files?

From the brainsmoke/hexboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Hexdump design in my own project?

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

Can I test firmware for the Hexdump 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.
