Pd test: common questions

What microcontroller does the Pd test use?

The Pd test is built around the ESP32-S3-DEVKITC, from the ESP32 family.

How big is the Pd test PCB?

The Pd test measures 107.2 × 83.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pd test?

67 components, from 49 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 Pd test design files?

From the Yuan-Quan/pet-climate-control repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Pd test design in my own project?

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

Can I test firmware for the Pd test 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.
