Swing: common questions
What microcontroller does the Swing use?
The Swing is built around the ATmega328PB-A, from the AVR/Arduino family.
How big is the Swing PCB?
The Swing measures 50 × 50 mm, has 4 copper layers and is 1.724 mm thick.
How many components are on the Swing?
146 components, from 75 distinct parts. The full bill of materials is listed on this page.
Where can I download the Swing design files?
From the lucanastasio/myHomeAutomation repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Swing design in my own project?
The repository has no license, so all rights stay with lucanastasio. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Swing 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.
