One of the first issues you'll want to consider is how to power the board. To do this, you need to connect through the USB power connection. There are two choices for providing power to the Raspberry Pi Zero:
- Connect the micro USB connector labeled power to a 5V DC source powered by a USB power supply. This can be either a power supply that can plug directly into an outlet, or power supplied by a powered USB port such as those available on most computers.
- Connect the micro USB connector to a battery. The simplest type of connection is to a battery that has a USB connector, like those used to charge cellphones. Here is an image of just such a battery:
In both cases, make sure that the unit can supply enough current. You'll need a supply that can provide at least 1000 mA at 5V. Do not plug in the board just yet; you first need to connect the rest of the hardware and configure the micro SD card. However, you are now ready to connect the rest of the hardware.
