Expansion¶
Cape Headers¶
The expansion interface on the board is comprised of two headers P8 (46 pin) & P9 (46 pin). All signals on the expansion headers are 3.3V unless otherwise indicated.
Note
Do not connect 5V logic level signals to these pins or the board will be damaged.
Note
DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.
Connector P8¶
The following tables show the pinout of the P8 expansion header. The SW is responsible for setting the default function of each pin. Refer to the processor documentation for more information on these pins and detailed descriptions of all of the pins listed. In some cases there may not be enough signals to complete a group of signals that may be required to implement a total interface.
The column heading is the pin number on the expansion header.
The GPIO row is the expected gpio identifier number in the Linux kernel.
Each row includes the gpiochipX and pinY in the format of X Y. You can use these values to directly control the GPIO pins with the commands shown below.
# to set the GPIO pin state to HIGH
debian@BeagleBone:~$ gpioset X Y=1
# to set the GPIO pin state to LOW
debian@BeagleBone:~$ gpioset X Y=0
For Example:
+---------+----------+
| Pin | P8.03 |
+=========+==========+
| GPIO | 1 20 |
+---------+----------+
Use the commands below for controlling this pin (P8.03) where X = 1 and Y = 20
# to set the GPIO pin state to HIGH
debian@BeagleBone:~$ gpioset 1 20=1
# to set the GPIO pin state to LOW
debian@BeagleBone:~$ gpioset 1 20=0
The BALL row is the pin number on the processor.
The REG row is the offset of the control register for the processor pin.
The MODE # rows are the mode setting for each pin. Setting each mode to align with the mode column will give that function on that pin.
NOTES:
DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.

Connector P9¶
The following tables show the pinout of the P9 expansion header. The SW is responsible for setting the default function of each pin. Refer to the processor documentation for more information on these pins and detailed descriptions of all of the pins listed. In some cases there may not be enough signals to complete a group of signals that may be required to implement a total interface.
The column heading is the pin number on the expansion header.
The GPIO row is the expected gpio identifier number in the Linux kernel.
Each row includes the gpiochipX and pinY in the format of X Y. You can use these values to direcly control the GPIO pins with the commands shown below.
# to set the GPIO pin state to HIGH
debian@BeagleBone:~$ gpioset X Y=1
# to set the GPIO pin state to LOW
debian@BeagleBone:~$ gpioset X Y=0
For Example:
+---------+----------+
| Pin | P9.11 |
+=========+==========+
| GPIO | 1 1 |
+---------+----------+
Use the commands below for controlling this pin (P9.11) where X = 1 and Y = 1
# to set the GPIO pin state to HIGH
debian@BeagleBone:~$ gpioset 1 20=1
# to set the GPIO pin state to LOW
debian@BeagleBone:~$ gpioset 1 20=0
The BALL row is the pin number on the processor.
The REG row is the offset of the control register for the processor pin.
The MODE # rows are the mode setting for each pin. Setting each mode to align with the mode column will give that function on that pin.
If included, the 2nd BALL row is the pin number on the processor for a second processor pin connected to the same pin on the expansion header. Similarly, all row headings starting with 2nd refer to data for this second processor pin.
NOTES:
DO NOT APPLY VOLTAGE TO ANY I/O PIN WHEN POWER IS NOT SUPPLIED TO THE BOARD. IT WILL DAMAGE THE PROCESSOR AND VOID THE WARRANTY.
NO PINS ARE TO BE DRIVEN UNTIL AFTER THE SYS_RESET LINE GOES HIGH.
