I suspect the answer has to be "no" to this...
But I guess there's really no way to use the LED pin 13 for status signalling once the WiFi101 shield is installed (...since it needs the SPI bus to commuincate with the controller)?
I was hoping something changed since similar questions were raised a while ago about SPI taking that pin?
Hi @zepto,
It really depends on the board you are using. The WiFi101 shield uses the ICSP header for SPI.
On some boards like the Uno pins 13 (SCK), 12 (MOSI), and 11 (MISO) are also connected to the same SPI pins and the ICSP header. Other boards like the Leonardo and Zero for example do not have 11 - 13 connected to the SPI pins, only the ICSP header.
Which board(s) do you plan to using with the WiFi101 Shield?
It's an Arduino 101 board. Pretty sure I'm out of luck... unless you know different

Hi @zepto,
Yes, looking at the 101's schematic, it does look like SCK is connected to pin 13 which is connected to the built-in LED.
Hi @sandeepmistry,
Thank you very much for checking that out for me. I'll be able to forget about that option now.
Seems I have some learning to do - i.e. reading schematics!
Best,
