ESP32AY: common questions

What microcontroller does the ESP32AY use?

The ESP32AY is built around the TP4056, from the ESP32 family.

How big is the ESP32AY PCB?

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

How many components are on the ESP32AY?

99 components, from 66 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 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 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 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.
