Is there any resource that lists shields that can be purchased or with open/public PCBs?
Particle has the more well known (presumably stable) ones listed in the store… but I’m curious about more indie stuff.
This is a nice proto-shield:
I also have the sparkfun one, but the form factor is a bit better for the above shield.
What else is out there? Is there a good SD card shield? It’d be simple to design. If it’s not out there should I make one?
