What would be the purpose of 2 transistors "in parallel" in the XBee shield from Libelium?
These are the 2 transistors (T1 and Q1) used to reset the microcontroller, from XBee's CTS output.
Plus, there are so many resistors in parallel. Why?
Thanks.

The two transistors are just different package types of the same device, one is thru-hole the other surface mount. The resistors without values are jumpers (0 ohm resistors) that you could insert if you want to drive the shield with 3.3 V.
I got it, smaht 
So there is one or the other installed, whatever they had on hand.
Good thing, I should use it myself on my boards as well. I am already thinking SMD/TH for (smaller, 8 pins) ICs, like DS1307.
Thanks.
