Esp32-iot board project: common questions

What microcontroller does the Esp32-iot board project use?

The Esp32-iot board project is built around the ESP32-C3-WROOM-02-H4, from the ESP32 family.

How big is the Esp32-iot board project?

The Esp32-iot board project measures 86.5 × 51.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Esp32-iot board project?

81 components, from 40 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-iot board project design files?

From the Iamshubham3/esp32-iot-board-project repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32-iot board project design in my own project?

The repository has no license, so all rights stay with Iamshubham3. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp32-iot board project 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.
