DoorbellCamPhy: common questions

What microcontroller does the DoorbellCamPhy use?

The DoorbellCamPhy is built around the ESP32-WROOM-32E (8MB), from the ESP32 family.

How big is the DoorbellCamPhy PCB?

The DoorbellCamPhy measures 81.6 × 97.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DoorbellCamPhy?

31 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the DoorbellCamPhy design files?

From the mc-cat-tty/DoorbellCamPhy repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the DoorbellCamPhy design in my own project?

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

Can I test firmware for the DoorbellCamPhy without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
