BeagleBone Black
7.2 Power Jack
The DC power jack is located next to the RJ45 Ethernet connector as shown in «昀椀gure-51». This uses the same
power connector as is used on the original BeagleBone. The connector has a 2.1mm diameter center post
(5VDC) and a 5.5mm diameter outer dimension on the barrel (GND).
Fig. 7.2: 5VDC Power Jack
The board requires a regulated 5VDC +/-.25V supply at 1A. A higher current rating may be needed if capes are
plugged into the expansion headers. Using a higher current power supply will not damage the board.
7.3 USB Client
The USB Client connector is accessible on the bottom side of the board under the row of four LEDs as shown
in «昀椀gure-52». It uses a 5 pin miniUSB cable, the same as is used on the original BeagleBone. The cable is
provided with the board. The cable can also be used to power the board.
This port is a USB Client only interface and is intended for connection to a PC.
7.4 USB Host
There is a single USB Host connector on the board and is shown in Figure 53 below.
The port is USB 2.0 HS compatible and can supply up to 500mA of current. If more current or ports is needed,
then a HUB can be used.
