2.4.1 Primary Radar Connector (J18)

The primary radar connector provides all of the reset, boot, digital control, and CSI2 signals from the primary radar device to the host (DCA2000EVM). This connector mates directly with the primary radar connector on the DCA2000EVM. In cases where the user wishes to mate the AWR2188EVM to the DCA2000EVM using cables, the recommended part number is the HDR-241659-03-HQCD cable from Samtec.
