ESP32AY-revD2: common questions

What microcontroller does the ESP32AY-revD2 use?

The ESP32AY-revD2 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the ESP32AY-revD2 PCB?

The ESP32AY-revD2 measures 55 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32AY-revD2?

127 components, from 52 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 ESP32AY-revD2 design files?

From the djspawnbrest/ESP32AY repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the ESP32AY-revD2 design in my own project?

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

Can I test firmware for the ESP32AY-revD2 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.
