Hi all!
I'm new to the hardware side of things. I'm working on an RGB matrix project using a 32x32 matrix, Metro M0 Express, and an RGB Matrix Shield.
Here's the problem - I need to make an API call from the Arduino, but it doesn't have any network connections built in (right?)!
So I'd like to add in a ESP8266 board, but that would require me wiring into pins on the Metro that are currently being used by the shield.
Is there a way around this? Or do I need to rethink my solution and maybe go with a MatrixPortal?
Thanks in advance!

Re: Metro Express + RGB Matrix + ESP8266
It's a tight fit but the SPI pins (SCLK, MISO, MISO) aren't used by the matrix shield you should be able to use D0 and/or D1 to let you add an Airlift breakout https://www.adafruit.com/product/4201.
But, you're right, a MatrixPortal is the ideal solution. It's essentially a Metro M4 Express, Matrix Shield (supporting up to 64x64 matrices) and an AirLift all in one very compact board. And completely plug-n-play.
