FaultLatcher: common questions

What microcontroller does the FaultLatcher use?

The FaultLatcher is built around the ATmega328P-AU, from the AVR/Arduino family.

How big is the FaultLatcher PCB?

The FaultLatcher measures 42.6 × 56.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the FaultLatcher?

39 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the FaultLatcher design files?

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

Can I use the FaultLatcher design in my own project?

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

Can I test firmware for the FaultLatcher without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
