3 Salient features of AoP EVM

Figure 3 shows the salient components of top and bottom side of the EVM.

EVM is divided into two sections:

  • Mission section
  • Break away section

Mission section contains key essential components for the mmWave sensor as shown in Figure 3. Break away sections contain switches, connectors, Analog muxes and TI Bluetooth® devices that are optional for the system design.
