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
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
