About the Easyduino Atmega Nano PCB

Easyduino Atmega Nano is an open source AVR/Arduino PCB design by Hanqaqa, published on GitHub under the CERN-OHL-P-2.0 license. It is a 4-layer board measuring 43.4 × 18 mm, with 30 components from 16 distinct parts.

Its main chip is the ATMEGA328P-A, from the AVR/Arduino family. Other key parts include the XC6206P502MR and CP2102N-AXX-XQFN28. By type, the board carries 12 capacitors, 7 resistors, 3 ICs, 3 diodes, 2 connectors and 1 crystal.

It belongs with the dev boards & breakouts and usb & debug tools designs in this gallery.

From the project

Easily dive into different PCB KiCad designs of the most popular microcontroller devboards

- Input Voltage: 5.5V-9V(External Source Vin) 5V (USB). Both can be used at the same time. Preferable to only power from one source - Output Current: 250 mA (External Source) 500mA (USB) - 3.3V Output Current: None (External Source) 100 mA (USB) - No Polarity Protection (External Source) - Overcurrent Protection: None (External Source) 1A (USB) - 5V Autoselector: can take both USB and external source. A diode will avoid short circuit. - External input Polarity Protection: None!!

Easyduino Atmega Nano: common questions

What microcontroller does the Easyduino Atmega Nano use?

The Easyduino Atmega Nano is built around the ATMEGA328P-A, from the AVR/Arduino family.

How big is the Easyduino Atmega Nano PCB?

The Easyduino Atmega Nano measures 43.4 × 18 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Easyduino Atmega Nano?

30 components, from 16 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 Easyduino Atmega Nano design files?

From the Hanqaqa/Easyduino 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 Easyduino Atmega Nano design in my own project?

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

Can I test firmware for the Easyduino Atmega Nano 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.
