Control panel: common questions

What microcontroller does the Control panel use?

The Control panel is built around the ATmega328PB-A, from the AVR/Arduino family.

How big is the Control panel PCB?

The Control panel measures 65 × 58 mm, has 2 copper layers and is 1.53 mm thick.

How many components are on the Control panel?

158 components, from 61 distinct parts. The full bill of materials is listed on this page.

Where can I download the Control panel 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 Control panel 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 Control panel 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.
