1) Power supply on lillypad
I know that working with accellerometers is a little bit dangerous: if you plug them to 5v instead of 3.3v you can burn them! So, before to plug and burn anything i want to ask if i have to do something to be sure. In normal Arduino board there are a physical pin to move for having 3.3v (or something that doesn't burn the accellerometer).
2) Physical disposition of resistors
I heave read in MMA8452Q_Example.pde (download here):
SDA and SCL should have external pull-up resistors (to 3.3V). 10k resistors worked for me. They should be on the breakout board.
and i'm thinking about what is the best way to put the resistors on such a tiny boards: i'm not good in soldering and i don't want to ruin the board, and i can't use a breadboard because it is a wearable project. what is the best? using some male pin strip (*)? Or shall i try to cut a little piece of Perfboard and solder over it? And how put the resitors near the accellerometer? or they could be also near arduino lillypad pins?
What can you advice me? I am quite totally new to electronics so any kind of advice or documentations is a valuable help.
