Athena HW: common questions
What microcontroller does the Athena HW use?
The Athena HW is built around the PIC32MX795F512L, from the PIC family.
How big is the Athena HW PCB?
The Athena HW measures 115.1 × 95 mm and is 1.6 mm thick.
How many components are on the Athena HW?
133 components, from 60 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 HW design files?
From the ffich/Athena_HW repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Athena HW design in my own project?
The repository has no license, so all rights stay with ffich. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Athena HW without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
