About the Valkyrie esp32s3 PCB

Valkyrie esp32s3 is an open source ESP32 PCB design by mindhashnl, published on GitHub. It is a 4-layer board measuring 110 × 178.4 mm, with 65 components from 25 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the CAT25160VI-GT3, TPSM33625RDNR and TS3USB30ERSWR. By type, the board carries 25 resistors, 20 capacitors, 7 switches, 5 ICs, 4 connectors and 3 diodes.

From the project

Yggdrasil is an open-source, modular hardware-in-the-loop (HIL) testing framework designed for continuous integration (CI/CD) of embedded systems. It allows developers to test firmware automatically on real microcontrollers (MCUs) at scale.

Yggdrasil is an open-source, modular hardware-in-the-loop (HIL) testing framework designed for continuous integration (CI/CD) of embedded systems. It allows developers to test firmware automatically on real microcontrollers (MCUs) at scale.

The physical architecture is designed to fit inside a standard 19-inch 3U server rack and consists of a primary control board, a multiplexing backplane, and hot-swappable target testing blades.

Valkyrie esp32s3: common questions

What microcontroller does the Valkyrie esp32s3 use?

The Valkyrie esp32s3 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Valkyrie esp32s3 PCB?

The Valkyrie esp32s3 measures 110 × 178.4 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the Valkyrie esp32s3?

65 components, from 25 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 Valkyrie esp32s3 design files?

From the mindhashnl/yggdrasil 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 Valkyrie esp32s3 design in my own project?

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

Can I test firmware for the Valkyrie esp32s3 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.
