MY-COOL-ESP32: common questions

What microcontroller does the MY-COOL-ESP32 use?

The MY-COOL-ESP32 is built around the ESP32-WROOM-32E-N8, from the ESP32 family.

How many components are on the MY-COOL-ESP32?

47 components, from 25 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 MY-COOL-ESP32 design files?

From the bhardwajpragya1111-lgtm/MY-COOL-ESP32 repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

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

The repository has no license, so all rights stay with bhardwajpragya1111-lgtm. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MY-COOL-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.
