About the DuinoCoinMiner PCB

DuinoCoinMiner is an open source ESP32 PCB design by samanbeer, published on GitHub. It is a 2-layer board measuring 81.1 × 61.8 mm, with 64 components from 10 distinct parts.

Its main chip is the XIAO-ESP32-C3-SMD, from the ESP32 family. Other key parts include the ATmega328P-AU. By type, the board carries 33 capacitors, 10 resistors, 7 ICs, 6 crystals, 6 switches and 1 transistor.

From the project

DuinoCoin miner

- What is it? It is a small PCB board with XIAO ESP32-C3 as main MCU for controlling 6 ATmega328P chips - What does it do? It mines crypto currency called Duino Coin. Which is a specialized coin that can be mined on any device like arduinos and lot more. You read about it on their site

3D printable case made in Fusion 360. All CAD and 3D model files (.f3z, .step) are in the CAD/ folder.

DuinoCoinMiner: common questions

What microcontroller does the DuinoCoinMiner use?

The DuinoCoinMiner is built around the XIAO-ESP32-C3-SMD, from the ESP32 family.

How big is the DuinoCoinMiner PCB?

The DuinoCoinMiner measures 81.1 × 61.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the DuinoCoinMiner?

64 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the DuinoCoinMiner design files?

From the samanbeer/DuinoCoinMiner repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the DuinoCoinMiner design in my own project?

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

Can I test firmware for the DuinoCoinMiner 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.
