Arduino MKR FOX 1200
The Arduino MKR FOX 1200 combines SigFox connectivity with the functionality of the Arduino MKR Zero. It is the ideal solution for beginners wanting to design IoT projects with a low power device.
The Arduino MKR FOX 1200 is based on the Atmel SAMD21 and an ATA8520 SigFox module. The intelligent design enables the ability to power the board using an external 5 V power supply or two 1.5 V AA or AAA batteries.
- 32-bit computational power
- Rich set of I/O interfaces
- Low power SigFox communication
- Automatic switch between the two sources
These features make this board an excellent choice for IoT battery-powered projects in a compact form factor. The USB port can supply power (5 V) to the board. The Arduino MKR FOX 1200 can run with or without the batteries connected and has limited power consumption.
Please note: Unlike most Arduino boards, the Arduino MKR FOX 1200 runs at 3.3 V. The maximum voltage the I/O pins can handle is 3.3 V. Applying voltages higher than 3.3 V to any I/O pin could damage the board. While output to 5 V digital devices is possible, bidirectional communication with 5 V devices needs proper level shifting

The Arduino MKR FOX 1200 requires a GSM antenna to be attached to the board with the micro UFL connector; please make sure that the antenna is compatible with the frequencies in the SigFox's range (868 Mhz).
Please note: Do not attach the antenna to a metallic surface
Batteries, Pins and board LEDs
- Battery capacity: The batteries must have a voltage of 1.5 V
- Battery connector: To connect a battery pack (2 x AA or AAA) to the Arduino MKR FOX 1200, use the screw terminal block.
- Polarity: On the silk in the bottom of the board, a positive pin is the closest to the USB connector
- VIN: This pin can power the board with a regulated 5 V source. If the power goes through this pin, the USB power source is disconnected. That is the only way to supply 5 V to the board, without using USB.
- 5 V: This pin outputs 5 V from the board when powered from the USB connector or the VIN pin.
- VCC: This pin outputs 3.3 V through the on-board voltage regulator. This voltage is 3.3 V if USB or VIN is used or equal the two batteries if they are used
- LED ON: The LED is connected to the 5 V input from either USB or VIN. It is not connected to the batteries. That results in the LED lighting up when the power comes from USB or VIN and staying off when the board is running on battery. That minimizes the waste of energy stored in the battery.
- Onboard LED: On Arduino MKR FOX 1200, the built-in LED is connected to D6 and not D13 as on the other boards. Blink example or other sketches that uses pin 13 for onboard LED may need to be changed to work properly.
