2.3.2 AWR2944 Evaluation Module

The AWR2944 EVM has the following features:

  • AWR2944 radar device
  • Onboard antenna (four transmitters and four receivers)
  • XDS110 based JTAG emulation with serial port for onboard QSPI flash programming
  • 60-pin, high-density (HD) connector for external JTAG and emulator interface with TRACE and CSI2 support
  • RJ45 connector to stream the captured data over the network to the host PC
  • MATEnet Ethernet interface to stream the captured data over the network to an automotive host
  • Dual onboard CAN-FD transceiver
  • 12-V power jack to power the board
