CDM324 Amplification Backpack, With Case and Simulations

cdm324_backpack's Issues

How can we do if we don't know how to use Isis

Hi, I'm a student and I want to know if it's possible to get the fritzing of this project.
Ty for you're answer.

Bad output

I made exactly as you did. With the same components, and I get nothing. If I connect fOut to analog pin I can see values from 509 to 512. CMD324 is the radar.

Have questions under the advice

See you this creation, really very powerful, I as an electronic enthusiast, but also want to do a play, but did not find your antenna file, the antenna with HB100 can? Thank you!

eagle or gerber files

Hi

Nice work, thanks for sharing.

I would like to test this sensor but don't have experience with kicad.
Any chance to have a Eagle version of the PCB? Or at least the GERBER files...

Thanks

Contact and Help pls

Hello Mathieu, I tried to send a message via LinkedIn, unfortunately it costs a lot of money there, so I hope I can reach you with this.

I live on a private street where many children play a lot, especially on Saturdays. The street is also marked that it is a dead end and private.
From the main road there is a supermarket right at the entrance to the private road and there is usually a huge rush of cars there on Saturdays.
Unfortunately, they also get lost on the private road and take out their shopping frenzy on the accelerator pedal there. I worry about my child and the children who play there worriedly in moments like this.
That's why I found this here from you and had the PCB made. I also get a level that I can read via VOUT with an ESP8266. However, I understood it to mean that the speed can only be measured to a decent extent with FOUT.
Unfortunately I don't get a signal there at the FOUT and I don't really know how to test it because I only have a voltmeter available.
I would like to attach a small LED matrix to the fence to show the vehicles their speed with smiles and to display a sad smile if the speed is too high. Hope you can still help me, even if the board is already outdated and replaced with a new one.

Do I have to activate the board via the nEN pin and if so, how?
Does it even work with an ESP8266?
Do I have to use all PINs like you did in the video, since only PIN 4 is specified in the Arduino Scetch?

I would be happy if you could help me, thank you very much!

If I want at 50 meters distance?

I got it But from the test, it can only work for 10 meters distance. If I want at 50 meters distance, what should I do? Please also recommend
