What DWM3000 module to choose

Wireless Connectivity Ultra-Wideband

Hi,

I would like to experiment with the DWM3000 module, but I am not sure which one to choose. Here’s what I need:

  1. To determine the position of a tag using multiple anchors (probably the TEST_DS_TWR_INITIATOR_STS example).
  2. To test positioning using PDOA.

If I understand correctly, for PDOA, I need a special kit with two antennas. Can I use the kit with two antennas for the TEST_DS_TWR_INITIATOR_STS example as well?

Which kit would you recommend? I will be using a Nucleo board as the host MCU to start with.

Thank you!

For PDOA, try this? QM33120WDK1 - Qorvo

You shall be able to get the PDoA in any STS enabled RX message through this example:
DW3_QM33_SDK_1.0.0\Drivers\API\Src\examples\ex_02h_simple_rx_pdoa

Thanks, so this one (DWM3000EVB) could be used only for distance measuring withou angle detection ok? https://cz.mouser.com/ProductDetail/Qorvo/DWM3000EVB?qs=iLbezkQI%252BsgO%252Bhh8kPU5Xg%3D%3D

Yes. DWM3000 is single antenna module so it can only do distance measurement. PDoA related measurements need at lease two antennas.
