MKR WAN 1300-board

MKR WAN 1300

The Arduino MKR WAN 1300 was the first LoRa® board released by Arduino, as a practical and cost effective solution with minimal power requirements. This open source board can connect to the Arduino IoT Cloud, your own LoRa® network using the Arduino LoRa® PRO Gateway, existing LoRaWAN® infrastructure like The Things Network, or even other boards using the direct connectivity mode.

The MKR WAN 1300 brings LoRa® connectivity to your projects. Using the popular Arm® Cortex®-M0 32-bit SAMD21 processor, it also features the powerful Murata CMWX1ZZABZ module and the ECC508 crypto-chip for security. The board is part of the MKR family, where you can choose from a large variety of shields to build projects out of the box with minimal effort!
Cortex-M0 32-bit SAMD21

The powerful, low-power processor that is used in all MKR Family boards.


Use the LoRa® wireless protocol for your own networks, or connect to various LoRaWAN® networks, such as The Things Network.

Crypto Chip
ATECC508 crypto chip

The ECC508 crypto chip makes sure your data remains secure and private, and can store up to 16 keys in an EEPROM array.
