Tutorial03-ESP32-IoT-4-layer: common questions

What microcontroller does the Tutorial03-ESP32-IoT-4-layer use?

The Tutorial03-ESP32-IoT-4-layer is built around the ESP32-C3-WROOM-02-H4, from the ESP32 family.

How big is the Tutorial03-ESP32-IoT-4-layer PCB?

The Tutorial03-ESP32-IoT-4-layer measures 88 × 55.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Tutorial03-ESP32-IoT-4-layer?

83 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tutorial03-ESP32-IoT-4-layer design files?

From the D76X/KiCad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Tutorial03-ESP32-IoT-4-layer design in my own project?

The repository has no license, so all rights stay with D76X. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Tutorial03-ESP32-IoT-4-layer 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.
