Siguino - the arduino designed for iot

Siguino is based on an Arduino Pro mini but designed specifically to be low power (to run on batteries only) and with a connection to the cloud via the SigFox network built in by default, including an on board aerial

What you will need

Step #1 IDE

Step #2 Powering Up

  • Connect FTDI interface to Siguino board with the 6 way ribbon cable.
  • Take care to connect the header pins in the correct order – they go in sequence.
  • DTR at one end and Ground at the other.
  • Ensure the 5V / 3.3V jumper is set to 3.3V.
  • Plug the USB cable into the FTDI header and into USB port on dev machine.
  • When powered up check the IDE menu Tools->Port again for a new entry.
    • Select this new entry if not already selected eg. /dev/ttyUSB0 (or USB1etc).
  • Click IDE top right icon‭ “‬Serial Monitor‭”‬.
  • On serial monitor window set‭ ‬9600‭ ‬baud on bottom right drop-down select box.
  • Dev ID and PAC Code‭ ‬response from Sigfox module ‭ ‬will ‬appear after a few seconds.‭
  • You will need to make a note of these for use during registration.
  • Power cycle by unplugging and re-plugging the USB cable if you missed it!
