LoRa® 32 bit ARM < 20 mA Microusb 3.3V Standard (~20) Regular

MKR WAN 1300 is a powerful board that combines the functionality of the MKR Zero and LoRa connectivity. It is the ideal solution for makers wanting to design IoT projects with minimal previous experience in networking having a low power device.

  • Overview
  • Tech Specs
  • Documentation
  • The Arduino MKR WAN 1300 board provides a practical and cost effective solution to add LoRa® connectivity to projects  requiring low power. This open source board can be connected 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.

    Small and Securely Connected

    The MKR WAN 1300, is based on the Microchip® SAMD21 low power processor, the Murata CMWX1ZZABZ LoRa® module, and the MKR family’s characteristic crypto chip (the ECC508).

    Arduino IoT Cloud

    Antenna

    The MKR WAN 1300 has to be used with GSM antenna that can be attached to the board with the micro UFL connector. Please check that it can accept frequencies in the LoRa's range (433/868/915 MHz). 

    Please note: for best result, do not attach the antenna to a metallic surface like car chassis, etc.

    Batteries, Pins and board LEDs

    Battery capacity: The connected batteries must have a nominal voltage of 1.5V 

    Battery connector: If you want to connect a battery pack (2x AA or AAA) to your MKR WAN 1300 use the screw terminal block.

    Polarity : as reported on the silk in the bottom of the board, positive pin is the closest to the USB connector

    Vin: This pin can be used to power the board with a regulated 5V source. If the power is fed through this pin, the USB power source is disconnected. This is the only way you can supply 5v (range is 5V to maximum 6V) to the board not using USB. This pin is an INPUT.

    5V: This pin outputs 5V from the the board when powered from the USB connector or from the VIN pin of the board. It is unregulated and the voltage is taken directly from the inputs. 

    VCC: This pin outputs 3.3V through the on-board voltage regulator. This voltage is 3.3V if USB or VIN is used and equal to the series of the two batteries when they are used

    LED ON: This LED is connected to the 5V input from either USB or VIN. It is not connected to the battery power. This means that it lits up when power is from USB or VIN, but stays off when the board is running on battery power. This maximizes the usage of the energy stored in the battery. It is therefore normal to have the board properly running on battery power without the LED ON being lit.

    Onboard LED: On MKR WAN 1300 the onboard LED is connected to D6 and not D13 as on the other boards. Blink example or other sketcthes that uses pin 13 for on board LED may need to be changed to work properly.
