Are there any practical limitations on how many shields can be stacked on a single Tinyduino, power, communications, etc?

Hi there,

There are some limitations to consider pin-wise. We have a compatibility matrix for all of our boards that aren't compatible with each other due to pin conflicts, and workarounds for some that are compatible with a few extra steps (mostly resistor/address changes):

Power can definitely be something to take into consideration when you are working with a battery-powered project, but many times you can make compromises on the project by limiting polling times or using low-power modes on devices/sensors that have those modes available - or getting a bigger battery if you can't make compromises. The current consumption information for all of our boards is available on the product pages under Tech Specs and in the dropdown Technical Details menu on each tutorial ( page - you can use the current consumption info to help you calculate how long a battery might last with your project, more discussion on that in this Arduino forum thread:

Feel free to ask more questions if you need more details on clarification on anything!
