Esp32-s3-testboard: common questions

What microcontroller does the Esp32-s3-testboard use?

The Esp32-s3-testboard is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Esp32-s3-testboard PCB?

The Esp32-s3-testboard measures 50 × 50 mm, has 4 copper layers and is 1.486 mm thick.

How many components are on the Esp32-s3-testboard?

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

Where can I download the Esp32-s3-testboard design files?

From the ktauchathuranga/esp32-s3-testboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32-s3-testboard design in my own project?

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

Can I test firmware for the Esp32-s3-testboard 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.
