Esp32io hw: common questions

What microcontroller does the Esp32io hw use?

The Esp32io hw is built around the ESP32-S3-DevKitC, from the ESP32 family.

How big is the Esp32io hw PCB?

The Esp32io hw measures 110 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32io hw?

85 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32io hw design files?

From the noritama-lab/esp32io-hw repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32io hw design in my own project?

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

Can I test firmware for the Esp32io hw 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.
