Product Data Sheet

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
Note
Please to correctly usage of the Flash memory follow these steps :
● saving data in ATSAMD21G18A ram
● shutting down the modem
● bringing up the flash and save the data there
