Better and More Efficient
The MKR WAN 1310, brings in a series of improvements when compared to its predecessor, the MKR WAN 1300. While still based on the Microchip® SAMD21 low power processor, the Murata CMWX1ZZABZ LoRa® module, and the MKR family’s characteristic crypto chip (the ECC508), the MKR WAN 1310 includes a new battery charger, a 2MByte SPI Flash, and improved control of the board’s power consumption.
Improved Battery Power
The latest modifications have considerably improved the battery life on the MKR WAN 1310. When properly configured, the power consumption is now as low as 104uA! It is also possible to use the USB port to supply power (5V) to the board; run the board with or without batteries - the choice is yours.
Data logging and other OTA (Over The Air) functions are now possible since the inclusion of the on board 2MByte Flash. This new exciting feature will let you transfer configuration files from the infrastructure onto the board, create your own scripting commands, or simply store data locally to send it whenever the connectivity is best. Whilst the MKR WAN 1310’s crypto chip adds further security by storing credentials & certificates in the embedded secure element.
These features make it the perfect IoT node and building block for low-power wide-area IoT devices.
If you are still deciding about the right wireless protocol for your solution, Arduino's MKR family has some alternatives to offer:
- MKR FOX 1200: for your EU solutions on Sigfox infrastructure. Visit its product page here.
- MKR GSM 1400: when looking at global coverage, GSM / 3G is the world's most extended network. Visit its product page here. We also provide you with a bundle including the board and a SIM with a global data plan in case you need it.
- MKR NB 1500: if your solution is designed around Narrowband IoT. Read more about it here.
The Getting Started section contains all the information you need to configure your board, use the Arduino Software (IDE), and start tinkering with coding and electronics.

Additional I2C Port
The MKR WAN 1310 has an additional connector meant as an extension of the I2C bus. It's a small form factor 5-pin connector with 1.0 mm pitch. The mechanical details of the connector can be found in the connector's datasheet.
The I2C port, also referred to as the Eslov self-identification port within Arduino, comes with: SDA, SCL, GND, +5V, and an extra digital pin meant to send an alarm to the otherwise plain I2C devices connected to it. The pinout is shown in the following image:
If you are interested in designing your own modules for Arduino boards with this expansion port, the connector we suggest using is code: SHR-05V-S-B, also in the picture.

When purchased at the Arduino Store, the MKR WAN 1310 comes bundled with an antenna that can be attached to the board using the existing micro UFL connector. It is possible to use other antennas using the appropriate pigtail.
When purchasing a different antenna than the one provided (or when making your own), please check that it is tuned for the frequency band in use in the LoRa® / LoRaWAN™ range (433/868/915 MHz). Also avoid placing your antenna in parallel to a ground plane like a large metallic surface.
Batteries, Pins and board LEDs
- Battery capacity: rechargeable Li-Ion, or Li-Po. Please make sure the battery connector suits your battery.
- Battery connector: The connector is of type JST S2B-PH-SM4-TB(LF)(SN). Mating connector is JST PHR-2.
- 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.
- 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, thus minimizing the impact on battery usage. It is therefore normal to have the board properly running on battery power without the LED ON being lit.
- Onboard LED: On MKR WAN 1310 the onboard LED is connected to D6.
