I have some work in progress KiCAD design of USB-C ESP32 devkit with doppler radar daughterboard:  I've used bit different radar design, which does not need any shapes on...
There was not much progress since in terms of design. The legal problems are mostly solved. I think i will need to review the files to see if all chips...
Yes, sorry. i am busy. i will try to share the design today even when not fully routed and tested. however we had some success with it in the past...
Ok, here are the files: [REF-radar.tar.gz](https://github.com/jdesbonnet/RCWL-0516/files/8859532/REF-radar.tar.gz) Some notes: * This comes with no warranty nor responsibility, it's just a prototype meant to be tuned and used by competent professionals *...
> Harvie, I'm confused about the purpose of this IC in the schematic. That is not IC. This is symbol which is associated with the radar RF footprint. Or you...
> That makes sense. Where in the PCB file is the BFR193 Q4? Only the Si2301CDS Q3 is present on the current layout. You are right. you wanted it quickly,...
Just pres this button in PCB  Then select "delete footprints without symbols" and "replace footprints with those specified in schematic" it will probably sync
> what is the inductance of the microstrip inductor (squiggly trace), and the parameters of the rectangular antenna traces? TBH i don't know, it will vary on different boards due...
> what your thought process was it was quite some time, but i beleive the original circuit used some application specific IC, which also had integrated amplifier along with other...
In theory it might be possible to detect if object moves towards the detector or away from it. That's something that should be possible using doppler effect used in this...
