Phobia: common questions

What microcontroller does the Phobia use?

The Phobia is built around the STM32F405RG, from the STM32 family.

How big is the Phobia PCB?

The Phobia measures 82.6 × 55.3 mm, has 8 copper layers and is 1.599998 mm thick.

How many components are on the Phobia?

165 components, from 57 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 Phobia design files?

From the rombrew/phobia-pcb 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 Phobia design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which rombrew chose for the repository.

Can I test firmware for the Phobia 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.
