Usb-2fa key: common questions

What microcontroller does the Usb-2fa key use?

The Usb-2fa key is built around the RP2350A, from the RP2040/RP2350 family.

How big is the Usb-2fa key PCB?

The Usb-2fa key measures 50.8 × 25.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Usb-2fa key?

36 components, from 18 distinct parts. The full bill of materials is listed on this page.

Where can I download the Usb-2fa key design files?

From the kermitsgonnakermicide/usb-2fa-key repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Usb-2fa key design in my own project?

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

Can I test firmware for the Usb-2fa key without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
