Athena: common questions

What microcontroller does the Athena use?

The Athena is built around the STM32F401RCT6, from the STM32 family.

How big is the Athena PCB?

The Athena measures 344.7 × 123.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Athena?

428 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 Athena design files?

From the BenjaminJAnderson/Orthodox 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 Athena design in my own project?

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

Can I test firmware for the Athena 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.
