Usb ps2: common questions

What microcontroller does the Usb ps2 use?

The Usb ps2 is built around the ATtiny85-20PU, from the AVR/Arduino family.

How big is the Usb ps2 PCB?

The Usb ps2 measures 31.2 × 15.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Usb ps2?

17 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the Usb ps2 design files?

From the semicontinuity/embedded 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 ps2 design in my own project?

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

Can I test firmware for the Usb ps2 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.
