The MKRFOX1200 is open-source hardware!
You can build your own board using the
in PNG format
The boards works on EU region. Check the EU coverage
on the SigFox website
The MKRFox1200 price includes a subscription to the SigFox network for two years. The plan will be automatically activated after the fourth message has been sent. You can send up to 140 messages per day.
The MKRFox1200 is shipped with a GSM antenna that can be connected to the board with the micro UFL connector. If you want to change the antenna please check that it can accept frequencies in the SigFox's range (868 Mhz).
Batteries, Pins and board LEDs
The connected batteries must have a nominal voltage of 1.5V
If you want to connect a battery pack (2x AA or AAA) to your
MKRFOX1200 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
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
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
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
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
On MKRFOX1200 the onboard LED is connected to
and not D13 as on the other
boards. Blink example or other sketcthes that uses
pin 13 for onboard LED may need to be changed
to work properly.
