AWRL6844EVM IWRL6844EVM Functional Block Diagram Figure 2-1 Functional Block Diagram

Figure 2-1 shows functional block diagram of xWRL6844EVM. The EVM contains all essential components for the TI mmWave radar system: PMIC, SFLASH, SOP configuration, filter for power supply, mmWave Radar Sensor, USB to UART converter and a 60-pin Samtec connector for interfacing with DCA1000. The xWRL6844EVM has a provision to mount a launch-pad booster-pack connector which can be connected to TI’s LaunchPad boards.
