ESP32-main: common questions

What microcontroller does the ESP32-main use?

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

How big is the ESP32-main PCB?

The ESP32-main measures 49.3 × 72.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-main?

28 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32-main design files?

From the tuengominh/esp32-dragon repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ESP32-main design in my own project?

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

Can I test firmware for the ESP32-main 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.
