MKR WAN 1300 is a powerful board that combines the functionality of the MKR Zero and LoRa / LoRaWANTM 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

Arduino MKR WAN 1300 has been designed to offer a practical and cost effective solution for makers seeking to add LoRa® connectivity to their projects with minimal previous experience in networking. It is based on the Atmel SAMD21 and a Murata  CMWX1ZZABZ Lo-Ra module.

The design includes the ability to power the board using two 1.5V AA or AAA batteries or external 5V. Switching from one source to the other is done automatically. A good 32 bit computational power similar to the MKR ZERO board, the usual rich set of I/O interfaces, low power LoRa® communication and the ease of use of the Arduino Software (IDE) for code development and programming. All these features make this board the preferred choice for the emerging IoT battery-powered projects in a compact form factor. The USB port can be used to supply power (5V) to the board. The Arduino MKR WAN 1300 is able to run with or without the batteries connected and has limited power consumption.

Warning: Unlike most Arduino & Genuino boards, the MKR WAN 1300 runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board. While output to 5V digital devices is possible, bidirectional communication with 5V devices needs proper level shifting.

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.

FAQs

Q: I plugged the board to my PC / MAC but I cannot see the serial port listed in the IDE, so I can't upload my sketch to the board!
A: The first thing to try is to manually put the board into bootloader mode, this is accomplished by quickly pressing the reset button twice (you may need a pencil to push the button). The second thing to try is to try another USB cable: some micro-USB cables are "power only", you'll see the board is powered but won't get a connection to the PC.

Q: I plugged the board, I can see the serial port but I cannot upload sketch
A: If still on, remove the conductive foam that protects the pins.

Q: What is the VIN voltage range?
A: VIN Nominal voltage value is 5V. It ranges from 5V to 6V (6V is the Maximum) 

Q: What does Vin, 5V and VCC mean?

  • 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 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. When powered from the battery it supplies around 3.7 V.  As an OUTPUT, it should not be used as an input pin to power the board.
  • VCC: This pin outputs 3.3V through the onboard voltage regulator. This voltage is the same regardless the power source used (USB, Vin or Battery).
