Power

You could supply the power through Micro USB Port or VBUS pin. The operation input voltage is minimum 3.55V, maximum 6V and maximum 500mA current (500mA resettable fuse is on the board) is capable for this board. If you drive the high current device like a big motor, you have to use the external power source with a relay circuit.

Micro-USB type B (5V) input is the most convenient way to supply the power. You can use the Travel Adapter for your smartphone (5V, 500mA or higher) or USB2.0/3.0 port which can supply more than 500mA. If you want to use the battery for the production, you should consider the voltage (3.55V ~ 6.0V) and current (up to your application).
