ESP32S3: common questions

What microcontroller does the ESP32S3 use?

The ESP32S3 is built around the LP0404N3T5G, from the ESP32 family.

How big is the ESP32S3 PCB?

The ESP32S3 measures 17.8 × 21.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32S3?

71 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32S3 design files?

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

Can I use the ESP32S3 design in my own project?

Yes, under the terms of its MIT license, which dhirptl chose for the repository.

Can I test firmware for the ESP32S3 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.
