Hardware Description
2.1.7 BoosterPacks and Headers
2.1.7.1 BoosterPack 1
The Crypto Connected LaunchPad features two fully independent BoosterPack XL connectors. BoosterPack 1, located around the ICDI portion of
the board, is fully compliant with the BoosterPack standard with the single exception of GPIO pin PA6 (X8-16), which does not provide analog
capability. PA6 is located near the bottom of the inner left BoosterPack XL header.
Inter-integrated circuit (I2C) is provided in both the original BoosterPack standard configuration as well as the updated standard location. Use of
I2C on the bottom left of the BoosterPack connections per the updated standard is highly encouraged whenever possible.
Motion control advanced PWM connections are provided on the inner right connector for motion control applications.
Table 2-1 provides a complete listing of the BoosterPack pins and the GPIO alternate functions available on each pin. The TM4C129ENCPDT
GPIO register GPIOPCTL values are shown for each configuration. The headers in this table are labeled from left to right in ten pin columns. ‘A’
and ‘D’ make up the outer BoosterPack standard pins, ‘B’ and ‘C’ make up the inner BoosterPack XL standard pins.
