The current consumption of mbed was measured.

Measurement condition
- Input voltage: 5V(Supply it from self power USB hub to VIN of mbed).
- The test environment: LED of four every five seconds is lit one by one. This is repeated.
- It takes the average measuring it five times.

Unit:mA
Understood thing
- When LED is not lit at all, the current consumption of mbed is about 139.10mA.
- When all of the four LED on the mbed substrate is lit, current consumption is about 147mA.
- Current consumption goes up by about 2mA at the time of each lighting LED 1 piece.
