CAPSTONE-2026: common questions

What microcontroller does the CAPSTONE-2026 use?

The CAPSTONE-2026 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the CAPSTONE-2026 PCB?

The CAPSTONE-2026 has 2 copper layers and is 1.6 mm thick.

How many components are on the CAPSTONE-2026?

39 components, from 30 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 CAPSTONE-2026 design files?

From the kolisahil2709/CAPSTONE-2026 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 CAPSTONE-2026 design in my own project?

The repository has no license, so all rights stay with kolisahil2709. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the CAPSTONE-2026 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.
