Arduino MKR WAN 1310

2.2 LoRa module

LoRa connectivity is provided by a Murata CMWX1ZZABZ module. This module contains a STM32L0

processor along with a Semtech SX1276 Radio. The processor is running on Arduino open source

firmware based on Semtech code.

2.3 Crypto (ECC508)

The crypto chip in Arduino IoT boards is what makes the difference with other less secure boards as it

provides a secure way to store secrets such as certificates and it also allows accelerating secure

protocols while never exposing secrets in plain text.

Source code for the Arduino Library that supports the Crypto is available here [10]

2.4 Flash Memory (W25Q16)

Arduino MKRWAN 1310 is available with additional external SPI Flash memories. External SPI flash can

provide up to 16Mb of storage and can be used as a SPI peripheral for data storage.

Source code for the Arduino Library that supports the Flash Memory is available here [11]

Note

Although Firmware is open source, modifying it will require recertification of the radio stack
