Xling: common questions

What microcontroller does the Xling use?

The Xling is built around the ATmega1284P-AU, from the AVR/Arduino family.

How big is the Xling PCB?

The Xling measures 35 × 47 mm, has 2 copper layers and is 1 mm thick.

How many components are on the Xling?

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

Where can I download the Xling design files?

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

Can I use the Xling design in my own project?

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

Can I test firmware for the Xling 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.
