I am using the awesome Particle Electron with a NFC Reader from Elechouse ( link ).
Now I have it connected via SPI and the regular 3.3V power port. But I would like to cut the current to it while the elctron sleeps (not sure how much power it uses when not reading but even the LED on the reader kind of annoys me ).
Could I power this reader via a GPIO Port somehow maybe so I can turn it on and off with WriteDigital?
Thanks a lot in advance!
