About the Hashdisk PCB

Hashdisk is an open source ESP32 PCB design by BeeEvolved, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 99.6 × 95.4 mm, with 86 components from 40 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the TPS546D24ARVFR, RT9080-33GJ5, MCP1824T-1202E/OT, MCP1824T-0802E and 25MHz. By type, the board carries 52 capacitors, 18 resistors, 9 ICs, 4 connectors, 2 switches and 1 inductor.

It belongs with the iot & wireless designs in this gallery.

From the project

An open source Bitcoin miner utilizing BM1370 ASIC chips, engineered with thermal management features to enhance performance and reliability.

In engineering, shapes matter. Consider why water and air are typically transported in pipes and tubes: rounded forms optimize flow dynamics, reduce friction, and provide structural integrity. The Hashdisk embraces these principles with a circular design that naturally complements modern infrastructure.

Unlike traditional Bitcoin mining devices, which are often bulky and square the Hashdisk’s sleek, rounded form not only enhances visual appeal but also improves functionality, especially when integrated into fluid or air transport systems.

Hashdisk: common questions

What microcontroller does the Hashdisk use?

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

How big is the Hashdisk PCB?

The Hashdisk measures 99.6 × 95.4 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Hashdisk?

86 components, from 40 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hashdisk design files?

From the BeeEvolved/hashdisk repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Hashdisk design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which BeeEvolved chose for the repository.

Can I test firmware for the Hashdisk 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.
