4.4 LaunchPad Connectors
On the bottom side of the ADS131A04EVM board is a set of unpopulated surface-mount connectors (J6 and J8). When populated, these devices can be used to connect to a TI LaunchPad directly as a typical BoosterPack™ plug-in module.
Connectors J6 and J8 are a set of 10x2, 100 mil connectors. As shown in Table 4-3, the pin numbers for J6 and J8 map to the pin numbers for a standard 40-pin LaunchPad connector. To align pin 1 of the launch pad to J6[1], which corresponds to +3.3V, the PHI connector (J5) on the ADS131A04EVM will face towards the top of the launchpad, and the launchpad will be placed underneath the ADS131A04EVM.
