Portfolio: common questions

What microcontroller does the Portfolio use?

The Portfolio is built around the ESP32-S3-DEVKITC-1, from the ESP32 family.

How big is the Portfolio PCB?

The Portfolio measures 191.8 × 123 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Portfolio?

252 components, from 62 distinct parts. The full bill of materials is listed on this page.

Where can I download the Portfolio design files?

From the megmem044/Portfolio repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Portfolio design in my own project?

The repository has no license, so all rights stay with megmem044. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Portfolio 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.
