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.
Universal node, plug and play extensions to ease sensors connection.
- 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 )
