ESP32AY-revD: common questions
What microcontroller does the ESP32AY-revD use?
The ESP32AY-revD is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the ESP32AY-revD PCB?
The ESP32AY-revD measures 55 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESP32AY-revD?
111 components, from 51 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-revD 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-revD 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-revD 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.
