 * Terminal Block - the gerber silkscreen doesn't show this well, but near the bottom of the board, a terminal block can be mounted, then connect the (+) terminal (on the left) to the positive terminal, then the (-) terminal (on the right) to the project.
 * Direct solder - instead of using the terminal block, wires can be soldered to these through-holes to be used as 'leads'.

 *  1ohm = 100mA Max Current with 25uA Resolution

-* 0.01 ohm = 10A Max Current with 2.5mA Resolution
+* 0.01 ohm = 10A Max Current with 2.5mA Resolution (ACTUALLY 5A MAX!) Though you 'could' measure 10A, that would burn up the 0.25W current sense resistor.  If you need to measure higher than 5A, then you might be able to get a 0.01ohm resistor with a higher power rating.
 Each of these resistors can be soldered onto a mini Current Sense Board, then based on the expected max current of the project, the appropriate Current Sense Board can be plugged into the Power Monitor Board.

 Though, the board shows 3V3, the board is also compatible with 5V systems.  This configuration from the datasheet was implemented:
