For my project,we need to start so kindly help us to know which module works for my needs ..There will be no signal interference.dw1000 vs dw3000
DW1000 is an IC, it requires some very careful PCB layout and appropriate support parts. This is what you would use if going for a fully custom design.
DWM1000 is a module containing a DW1000 IC and the required external parts (antenna, 38.4 MHz clock, capacitors etc…). You need to supply 3.3V and send commands over SPI from your own processor to get it to do anything. This gives you a simple way to interface to the device without all the complications of having to lay out a PCB for it.
You need to write your own firmware. There are example drivers (that may or may not work without modification depending on the processor you use) and basic examples for how to measure ranges.
DWM1001 is a module containing both a DW1000 IC and a processor. There is some off the shelf firmware for that processor (PANS) that will give you a full positioning system that has all the required approvals for use in a commercial product. The disadvantage of this is that the firmware is closed source and locked down in order to ensure it can’t violate those approvals.
You can also write your own firmware, this has the advantage over the DWM1000 in that you are using a known good hardware design that lots of other people and examples will be using. The disadvantage is you can’t then change processor or other hardware features.
DM3000 is a newer version of the device, a DMW3000 exists that is equivalent to the DWM1000.
The DW3000 drops support for the ~4GHz band (channels 1-4) and adds support for a ~8 GHz band (channel 9). Channel 9 has more global approvals and is clear from potential 5G interference that can impact the lower frequency bands. Higher frequencies give slightly shorter ranges.
The DW3000 also drops support for 110 kbs data rate (very slow but gives better range) and adds support for encryption for more secure ranging / spoofing prevention.
There is a version of the DW3000 that supports twin antennas enabling angle of arrival measurements.
What should you use? Unless you need one of the specific features that were added/removed there is no strong requirement to use one part of the other, in terms of basic capabilities and ease of use they are very similar. If you configure them to use the common channel (channel 5, 6.5 GHz) it is possible to have a DW1000 and a DW3000 work with each other. There is generally a little more support for the DW1000 but there isn’t much in it.
I would highly recommend using the DWM1000/3000 rather than the using the IC directly. depending on how much hardware work you want to do and exactly what your application requirements are the DWM1001 may be a good choice to reduce risk.
Hi @VARSH
on the top of @AndyA answer I would like to add one thing - there is a new devkit for DW3000 products The QM33120WDK2 - Qorvo It contains a newer version of RTLS stack with much more features and it supposed to be maintained for a longer time. While the PANS is not maintained anymore for a long time.
Cheers
