FailDeadly: common questions

What microcontroller does the FailDeadly use?

The FailDeadly is built around the STM32F401CCUx, from the STM32 family.

How big is the FailDeadly PCB?

The FailDeadly measures 70 × 25 mm, has 4 copper layers and is 1.569 mm thick.

How many components are on the FailDeadly?

92 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the FailDeadly design files?

From the yvoronkin/FailDeadly repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the FailDeadly design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the FailDeadly 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.
