ti,boosterpack-header¶

Description¶

TI BoosterPack GPIO header

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:

1  3.3V     21 5V                    40 GPIO 20 GND

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
