EVM Description and Basics

www.ti.com

The simple diagram of Figure 1 shows only the basic features of the USB-MODEVM Interface board.

When connecting the TLV320AIC3007EVM to the USB-MODEVM, use care to avoid bending theconnecting pins. The two boards can only be connected in one way. It is suggested to first align with the10-pin connectors (J3 on the TLV320AIC3007EVM and J18A on the USB-MODEVM) and then gentlypush all the connectors together until the boards are seated.

In the factory configuration, the board is ready to use with the TLV320AIC3007EVM. To view all thefunctions and configuration options available on the USB-MODEVM board, see the USB-MODEVMInterface Board schematic in Appendix E.
