3 EVM Connectors

This section describes the connectors, jumpers, and test points on the EVM as well as how to connect, set up,

and properly use the EVM. Each device has an independent supply connection, but all grounds are connected

on the board.

3.1 EVM Test Points

Table 3-1 lists the EVM test points as well as their functional descriptions. All TPS38700-Q1 pins have a

corresponding test point on the EVM. These test points are located close to the pins for more accurate

measurements. In addition to the test points listed below, the EVM also has four additional GND test points.
