Lynx-PS2: common questions

What microcontroller does the Lynx-PS2 use?

The Lynx-PS2 is built around the ATMEGA328, from the AVR/Arduino family.

How big is the Lynx-PS2 PCB?

The Lynx-PS2 measures 75.9 × 76.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lynx-PS2?

23 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lynx-PS2 design files?

From the Board-Folk/Camputers-Lynx repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Lynx-PS2 design in my own project?

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

Can I test firmware for the Lynx-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.
