About the Esp32stack PCB

Esp32stack is an open source ESP32 PCB design by asukiaaa, published on GitHub. It is a 2-layer board measuring 3.2 × 3.2 mm, with 27 components from 16 distinct parts.

Its main chip is the ESP32-WROOM, from the ESP32 family. Other key parts include the NCP1117ST33T3G and CP2102. By type, the board carries 8 capacitors, 6 resistors, 3 ICs, 3 connectors, 3 diodes and 2 transistors.

It belongs with the dev boards & breakouts and usb & debug tools designs in this gallery.

Esp32stack: common questions

What microcontroller does the Esp32stack use?

The Esp32stack is built around the ESP32-WROOM, from the ESP32 family.

How big is the Esp32stack PCB?

The Esp32stack measures 3.2 × 3.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32stack?

27 components, from 16 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 Esp32stack design files?

From the asukiaaa/esp32stack repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Esp32stack design in my own project?

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

Can I test firmware for the Esp32stack 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.
