Test Set Up www.ti.com
If two EVM boards are stacked together, the other EVM is configured as a slave as shown in Figure 7.
Figure 7. Configure the EVM as a Slave for Stackable Operation
If more than two EVM boards are stacked, for example three, the two slave EVMs have slightly different
settings. Considering the master is the first board in the chain and all others are slaves, JP4 in the last
slave board should be shorted by a jumper while it is left as open in other slave boards. The
configurations are shown in Figure 8.
Figure 8. Master and Slave Connection (this EVM is the slave)
J5 and J6 are used to connect the EVM to the other EVM boards. Male-to-male headers are provided to
make the connections between the boards.
