title: TI BoosterPack GPIO header

description: |
    GPIO pins exposed as BoosterPack headers on TI LaunchPads.

    BoosterPack plug-in modules are available in 20 and 40 pin variants. The
    20 pin variant has two 10 x 1 pin headers and the 40 pin variant has two
    10 x 2 pin headers. Both variants are compatible and stackable.

    The pins of the 20 pin variant and the outer row of the 40 pin variant are
    numbered 1 through 20. The inner rows of the 40 pin variant are numbered 21
    through 40. The BoosterPack pinout is depicted below:

    2  Analog   22 GND                   39 GPIO 19 GPIO / SPI CS
    3  UART RXD 23 Analog                38 GPIO 18 GPIO
    4  UART TXD 24 Analog                37 GPIO 17 GPIO
    5  GPIO     25 Analog                36 GPIO 16 RESET
    6  Analog   26 Analog                35 GPIO 15 SPI MOSI
    7  SPI CLK  27 Analog                34 GPIO 14 SPI MISO
    8  GPIO     28 Analog                33 GPIO 13 GPIO / SPI CS
    9  I2C SCL  29                       32 GPIO 12 GPIO / SPI CS
    10 I2C SDA  30                       31 GPIO 11 GPIO
