2024-04-20 RCWL-0516 Microwave Doppler Motion Sensor Module Schematic KO4BB

The modules use both the RCWL-9616 and the BISS-0001 but it seems the schematics are all labeled BISS-0001.  The parts values are different.  He gives some good information about them.  They operate at 3.5 and 3.98 GHz – the ones I have were advertised at 5 GHz.  Also he shows his own version that uses a dual opamp.
