Easyduino ESP32: common questions

What microcontroller does the Easyduino ESP32 use?

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

How big is the Easyduino ESP32 PCB?

The Easyduino ESP32 measures 28.4 × 47.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Easyduino ESP32?

29 components, from 15 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 Easyduino ESP32 design files?

From the Hanqaqa/Easyduino 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 Easyduino ESP32 design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which Hanqaqa chose for the repository.

Can I test firmware for the Easyduino ESP32 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.
