About the DUINO PCB

DUINO is an open source AVR/Arduino PCB design by elVucko, published on GitHub under the MIT license. It is a 4-layer board measuring 50 × 50 mm, with 87 components from 21 distinct parts.

Its main chip is the ATMEGA328P-AU, from the AVR/Arduino family. Other key parts include the CH340C and FE1.1S. By type, the board carries 30 resistors, 19 capacitors, 14 diodes, 9 ICs, 9 crystals and 6 connectors.

It belongs with the usb & debug tools designs in this gallery.

This is the simplest DUINO coin mining board design with four Atmega328p and CH340 connected to the FE1.1S USB hub. All that's needed to mine with this board is a micro USB/USB A cable to connect with a computer and the AVR_Miner application installed. One version of the PCB is with CH340C and for me, that version works great. But only the CH340C can be used here. Due to difficulties in buying quality chips, I did another design where CH340G is used. On this PCB, both versions of CH340 can be used without any problems. I made this design for fun and I hope it can be useful to someone.

DUINO: common questions

What microcontroller does the DUINO use?

The DUINO is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the DUINO PCB?

The DUINO measures 50 × 50 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the DUINO?

87 components, from 21 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 DUINO design files?

From the elVucko/Duino_Coin_AVR 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 DUINO design in my own project?

Yes, under the terms of its MIT license, which elVucko chose for the repository.

Can I test firmware for the DUINO without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
