Door ext photorelay: common questions

What microcontroller does the Door ext photorelay use?

The Door ext photorelay is built around the ATMEGA328P-PU, from the AVR/Arduino family.

How big is the Door ext photorelay PCB?

The Door ext photorelay measures 57 × 47 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Door ext photorelay?

23 components, from 9 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Door ext photorelay design files?

From the zam-haus/door_pi repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Door ext photorelay design in my own project?

Yes, under the terms of its GPL-3.0 license, which zam-haus chose for the repository.

Can I test firmware for the Door ext photorelay 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.
