The Arduino MKR WAN 1310 board provides a convenient and cost-effective solution to add Lora® connectivity to projects that require low power consumption. This open source board can be connected to the Arduino IoT Cloud, your own Lora® network using the Arduino Lora® PRO gateway, an existing LoRaWAN infrastructure such as The Things Network, or even other boards using Direct Connectivity mode.The MKR WAN 1310 brings a number of improvements compared to its predecessor, the MKR WAN 1300. The MKR WAN 1310 is still based on the Microchip® SAMD21 Low Power Processor, Murata CMWX1ZZABZ Lora® Module and the MKR family's characteristic crypto chip (the ECC508), but has a new battery charger, a 2 MB SPI flash and improved regulation of the board's power consumption.The last modifications have significantly improved the battery life of the MKR WAN 1310. With the correct configuration, the power consumption is now only 104uA! It is also possible to supply the board with power (5V) via the USB po
