Esp32-s3-board nowireless: common questions

What microcontroller does the Esp32-s3-board nowireless use?

The Esp32-s3-board nowireless is built around the ESP32-S3, from the ESP32 family.

How big is the Esp32-s3-board nowireless?

The Esp32-s3-board nowireless measures 65 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-s3-board nowireless?

55 components, from 23 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-s3-board nowireless design files?

From the Hita-haru/esp32-s3-board-nowireless 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-s3-board nowireless design in my own project?

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

Can I test firmware for the Esp32-s3-board nowireless 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.
