Generic node: common questions

What microcontroller does the Generic node use?

The Generic node is built around the ATmega328PB-M, from the AVR/Arduino family.

How big is the Generic node PCB?

The Generic node measures 48.9 × 17.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Generic node?

47 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Generic node 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 Generic node 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 Generic node 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.
