2.4.1 Hardware Block Diagram

The TIDEP-01025 is implemented for AWR1843BOOST, AWR6843ISK and IWR6843ISK EVM. The EVM needs to be connected to a host PC through universal asynchronous receiver-transmitter (UART) for MetaImage load and log collection.

The AWR1843BOOST/xWR6843ISK includes the following features:

  1. AWR1843 Radar Device on AWR1843BOOST, IWR6843/AWR6843 Radar Device on xWR6843ISK.
  2. Power management circuit to provide all the required supply rails from a single 5-V input
  3. Three onboard TX antennas and four RX antennas
  4. Onboard XDS110 that provides a JTAG interface, UART for sending Diagnostic test and Monitor report from mmWave device.
