Electronic – How to blink LED with 1.8V


I am experimenting with an Intel Edison mini breakout board with pinout like here: http://fab-lab.eu/wp-content/uploads/2014/10/Edison_IO_LED.jpg

Now, I soldered header pins to plug the board into a breadboard. Unfortunately, the GPIO levels are only 1.8V.

  • What should I do to make a LED blink from here (on a breadboard ideally)?
  • What else can be done with 1.8V GPIO levels?

UPDATE: It works with a BC547

However, depending on the blink frequency, it seems that LED does not turn ON completely. Might it be because the base resistor is 0 ?

1.8V is enough to drive a transistor which can be used to power all kinds of loads. Example:
