For the STSPIN stepper breakout board, we need some current sense/limiting resistors. These are special resistors that are very low resistance but very high wattage, so they can dissipate the heat from the Resistance * Current^2. One thing we need to optimize for in this project is space over price - since the board size is fixed. So let's find the smallest current sense resistor we can, we might discover some interesting things!
