I plan on running an IR LED off of the VCC pin (~5V), with appropriate limiting R. But I also want to run VCC to a few LED driver transistors, to be switched on/off using IO pins. Total current for all would be ~100mA. Am I right in thinking that, when this combo is powered directly from USB, that the VCC *is* the raw USB 5v? Even if so, there could be current limits imposed by trace widths etc. I've looked around quite a bit but haven't seen anything definitive about this. Thanks for any help!

Hello,
VCC is the 5V connection as you suspected on the TinyDuino. You should be fine to supply around ``~100mA, you could go up to 500mA, but working around the upper limit can cause damage to the components.
Let me know if you have any other questions!
Thanks,
