## Features
- Compile and flash with Arduino IDE
- MCU = ATMega328P-AU
- radio = RN2483 / RFM69CW ( communications based on LoRaWan or MySensors protocol )
- 3.3V regulation ( XC6206P332MR )
- Powered by 3.7V LiPo battery ( 2 pins JST connector )
- Battery charging ( MCP7831 )
- State LED's
- Jumpers to activate radio reset, LED's, on/off switch
- Button for reset / config mode, or anything else!
- ATSHA204 to allow hardware unique signature ( no use with RN2483 )## Projects

Questions
How big is the Cosmonode ext02 PCB?
It measures 48.3 × 31.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cosmonode ext02 use?
24 parts, built around the XC6206P502MR and BSS138. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Cosmonode ext02 KiCad files?
From the exostic/Cosmonode_PCBs repository on GitHub, at the commit this page was made from: the board is Cosmonode_ext02/Cosmonode_ext02.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cosmonode ext02 design in my own project?
Its repository states no licence, so its author keeps all rights: ask exostic before reusing the design.
