Hardware setup

To boot BeagleBone Black, we need the following hardware:

An SD card with images flashed
BeagleBone Black
A power adapter that can supply 5V or a micro USB cable; we should use a 5V power adapter in order to avoid a decrease in the operating frequency
USB TTL-2303(PL2303) for serial communication

USB-TTL is connected to the J1 connector of BeagleBone in the following formation:

J1 Pin	USB TTL Function
1	GND Ground
4	RXL
5	TXL

A micro USB cable should be enough in most of the cases to provide power. However, for more resource-intensive tasks, for example, if additional peripherals are required, you will need to connect a power adapter.

Tip

Be careful when using PL2303 pins for current; otherwise, you may end up damaging your BeagleBone.
