Types of Pins on the BeagleBone Black

Power Pin BeagleBone Black

The BeagleBone Black features two expansion headers, P8 and P9, each providing 46 pins for 3.3V I/O signals. Applying 5V to any pin can damage the board.

Power Input: The BeagleBone Black accepts power through a DC power jack and a USB port, each with different power input ratings.

Power Output: The board offers three power output pins for external devices:


  1. The first pin provides 3 volts, sourced directly from the Low Dropout Regulator (LDO), suitable for devices with a maximum current rating of 250mA. For higher-current devices, an external power source is recommended.
  2. The second power port provides 5 volts and is directly connected to the DC jack power supply pin. No power is present on this pin when the device is powered via USB. The current on this pin depends on the DC power input but is limited to 1000mA.
  3. The third power port utilizes a regulator and receives power from both USB and DC inputs. The voltage is 5 volts, but the current depends on the power input.


All these power pins are available in multiple locations:


In P9:

  • +3.3V – Pin 3, Pin 4
  • +5V (VDD) – Pin 5, Pin 6
  • +5V (SYS) – Pin 7, Pin 8


Ground: Multiple ground pins are necessary for proper operation, and BeagleBone Black provides several interconnected ground pins for peripherals:

  • In P8:

DGND – Pin 1, Pin 2, Pin 43, Pin 44, Pin 45, Pin 46

  • In P9:

DGND – Pin 1, Pin 2


Power Button: The board includes a power button to safely shut down the device by saving all data. The power button is located in the P9 expansion header:

  • PWR_BUT – Pin 9


Reset Button: An external reset button restarts the device safely. The reset button is located in the P9 header:

  • SYS_RESETN – Pin 10



Digital Input/Output: The device offers 69 I/O pins, with the remaining pins reserved for other predefined functions. These I/O pins operate at 3.3 volts. The following table lists all the I/O pins available on the BeagleBone Black.

MMC Support Pins BeagleBone Black

It stands for Multimedia Card/SD Card Association (MMCA). In the BeagleBone Black, there is an embedded 2GB eMMC (embedded MultiMediaCard) that allows the device to boot from the built-in eMMC instead of an SD card. The eMMC is the default boot mode directly connected to the processor port. However, in the case of an SD card, the default mode will not be used because the eMMC is 8-bit and requires specific pins to operate. The third MMC, MMC2, will be used by other modules, as only MMC1 has external pins for operation. All MMC1 pins are located in Header P8.


  • MMC1_CMD – Pin20

BB HDMI LCD Interface Pins

The BeagleBone can be utilized to drive an LCD through HDMI. However, some pins dedicated to the HDMI framer are repurposed for other functions. Therefore, if these pins are used for other purposes, the framer will operate differently than expected since these pins are intended for input signals. All these pins are located in Expansion Header P8, listed below:


  • LCD_VSYNC – Pin27
  • LCD_PCLK – Pin28
  • LCD_HSYNC – Pin29

In the BeagleBone, analog signals can be directly converted to digital signals. It features a total of 7 A/D channels, all utilizing a single 12-bit ADC channel that must be activated first by providing 1.8V power through the ADC power pins. All ADC channels and power pins are located in expansion header P9, listed below:


  • AIN0 – Pin39
  • AIN1 – Pin40
  • AIN2 – Pin37
  • AIN3 – Pin38
  • AIN4 – Pin33
