4.2 BoosterPack Headers

Figure 4-2. BoosterPack Header Pinout

The AM243x LaunchPad supports two fully independent BoosterPack XL connectors. BoosterPack site #1
(J1/J3, J2/J4) is located in between the SoC and the bootmode DIP switch. BoosterPack site #2 (J5/J7, J6/J8)
is located in between the SoC and the RJ45 connectors. The GPIO pin numbers as well as the the BoosterPack
compliant features are listed in

. Each GPIO has multiple functions available through the GPIO mux.

The signals connected from the SoC to the BoosterPack headers include:
• SPI0 and SPI3
• UART0 and UART2
• I2C0 and I2C1
• MMC1
• ADC0
• EHRPWM0_A/B and EHRPWM1_A/B
• GPIO's
• 5 V and 3.3 V power supplies
