    The MKR GSM 1400 is open-source hardware! You can build your own board using the following files:

    The MKR GSM 1400 has to be used with a GSM antenna that can be attached to the board with the micro UFL connector. Please check that it can accept frequencies in the GSM's range (880/915 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 battery must be a 3.7V LiPo

    Vin: This pin can be used to power the board with a regulated voltage source rated at 5V. If the power is fed through this pin, the USB power source is disconnected. This is the only way you can supply MAXIMUM 5V 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 input voltage source from either USB or VIN. It is also connected to the battery power. This means that it is ON (with a lower intensity) also when the battery is inserted.

    Onboard LED: On MKR GSM 1400 the on board 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.

    Additional I2C Port 

    The MKR GSM 1400 has an additional connector meant as an extension of the I2C bus. It's a small form factor 5-pin connector with 1.0mm pitch. The mechanical details of the connector can be found in the connector datasheet.  The I2C port in addition to the SDA and SCL signals includes the GND and +5V power rails and a digital pin that might be useful when designing an expansion.  The pinout is shown in the following image: 

    The connector we suggest for this additional I2C Port is the SHR-05V-S-B, also in the picture.
