Esp32-wroom-32-usb development board: common questions

What microcontroller does the Esp32-wroom-32-usb development board use?

The Esp32-wroom-32-usb development board is built around the ESP32-WROOM-32E-H4, from the ESP32 family.

How big is the Esp32-wroom-32-usb development board?

The Esp32-wroom-32-usb development board measures 51.8 × 31 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-wroom-32-usb development board?

29 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 Esp32-wroom-32-usb development board design files?

From the Habib-creater/esp32-wroom-32-usb-development-board 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 Esp32-wroom-32-usb development board design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which Habib-creater chose for the repository.

Can I test firmware for the Esp32-wroom-32-usb development board 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.
