3.4 LaunchPad™ Connectors

On the bottom side of the ADS131B04-Q1EVM board is a set of unpopulated surface-mount connectors (J7 and J8). When populated, these devices can be used to connect to a TI LaunchPad directly as a typical BoosterPack™ plug-in module.

Connectors J7 and J8 are a set of 10x2, 100 mil connectors. As shown in Table 7, the pin numbers for J7 and J8 map to the pin numbers for a standard 40-pin LaunchPad™ connector.
