Four blue LEDs that can be controlled via the SW by setting GPIO pins.
In addition, there are two LEDs on the RJ45 to provide Ethernet status indication. One is
yellow (100M Link up if on) and the other is green (Indicating traffic when flashing).
5.12 CTI JTAG Header
A place for an optional 20 pin CTI JTAG header is provided on the board to facilitate the
SW development and debugging of the board by using various JTAG emulators. This
header is not supplied standard on the board. To use this, a connector will need to be
soldered onto the board.
If you need the JTAG connector you can solder it on yourself. No other components are
needed. The connector is made by Samtec and the part number is FTR-110-03-G-D-06.
You can purchase it from http://www.digikey.com/.
5.13 Grove Interfaces
There are two Grove connectors on the board:
I2C…The J4 connector is I2C interface. It accesses to the processor’s I2C2 interface
and also connect with the P9 expansion header’s I2C2 pins. The Grove I2C connector
is for the connection of Grove sensors with I2C interface.
Uart…The J5 connector is UART interface. It accesses to the processor’s UART2
interface and also connect with the P9 expansion header’s UART2 pins. The Grove
UART connector is for the connection of Grove sensors with UART interface.
Because of I2C and UART Interface can be setup to GPIO , the Groves with Digital interface
are supported for both Connectors.

5.14 Cape Board Support
The BeagleBone Green has the ability to accept up to four expansion boards or capes that
can be stacked onto the expansion headers. The word cape comes from the shape of the
board as it is fitted around the Ethernet connector on the main board. This notch acts as
a key to ensure proper orientation of the cape.
