CDM324 Microwave Module, 24GHz 15m Smart Microwave Body Induction Module Single Channel Switch Intelligent Sensor Module

Faulty Product, forced to reverse engineer pinout and refer to datasheets of similar modules available on the internet. Regardless, the module was faulty and never worked. Maybe it's just the module I received, but this module draws around 110mA, which is way out of spec, on top of that, there is no output.

Used for an Arduino project. Could not get an accurate reading at all and could not get a signal on any objects over 6 inches away.

It does what it says but lacks the ability to do much other than detect the presence of something in the path of the radar. Angle of arrival and distance aren’t really feasible without good documentation and the drivers for this on GitHub will require customized modifications to your specific needs.

No pinout. No silkscreen. No answer to my question. Yes I watched the video from TheSignalPath. His unit had the case connected to the ground pin. None of the pins on my unit are connected to the case. I've found two different references to this module online, and they each have the power and ground pins reversed. I shouldn't have to desolder the lid and take the thing apart to find out how to connect it. Would including a pinout on the silkscreen or on a piece of paper really be that hard?

While this module may be good for educational science experiments found on YouTube, it falls short in practical applications. To achieve a digital level signal, an additional circuit comprising two operational amplifiers is necessary. The product description could be enhanced by clearly stating this requirement and providing guidance on usage. As is, it was misleading and I have to return the device.
