About the Cosmonode ext05 PCB

Cosmonode ext05 is an open source AVR/Arduino PCB design by exostic, published on GitHub. It is a 2-layer board measuring 38.1 × 34.3 mm, with 22 components from 16 distinct parts.

Its main chip is the ATMEGA328P-AU, from the AVR/Arduino family. By type, the board carries 6 connectors, 5 diodes, 4 capacitors, 4 resistors, 1 IC and 1 crystal.

It belongs with the sensors designs in this gallery.

From the project

Kicad plans to design a base node as the main PCB. It also contains extensions adapted for different set of sensors/connectors.

Extension 5 : - ISP header for bootloader transfer and - micro USB for serial programming

Cosmonode ext05: common questions

What microcontroller does the Cosmonode ext05 use?

The Cosmonode ext05 is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the Cosmonode ext05 PCB?

The Cosmonode ext05 measures 38.1 × 34.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cosmonode ext05?

22 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 Cosmonode ext05 design files?

From the exostic/Cosmonode_PCBs repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Cosmonode ext05 design in my own project?

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

Can I test firmware for the Cosmonode ext05 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.
