Devkit2: common questions

What microcontroller does the Devkit2 use?

The Devkit2 is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.

How big is the Devkit2 PCB?

The Devkit2 measures 40.8 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Devkit2?

13 components, from 9 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 Devkit2 design files?

From the jacobjuneau6/devkit2 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 Devkit2 design in my own project?

Yes, under the terms of its MIT license, which jacobjuneau6 chose for the repository.

Can I test firmware for the Devkit2 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.
