Arduino MKR WAN 1310 [ABX00029]

  • The perfect IoT node and building block for adding to Lo-Ra connectivity to low power wide area IoT devices.
  • Very long battery life - the latest low power architecture means the power consumption is able to go as low as 104uA for extended battery life. It is also possible to use the USB port to supply power (5V) to the board, so you can run the board with or without batteries.
  • Local storage - On board 2MByte Flash to facilitate data logging and Over-The-Air (OTA) functions.
  • Enhanced Security - credentials and certificates are stored in the boards crypto chip, an embedded secure element.
  • Powerful - The MKR WAN1310 is based on the Atmel SAMD21 microcontroller and a Murata CMWX1ZZABZ Lo-Ra module.
