Power Supply Notes: The power supply input can use either 3.3 V or 5 V. To determine which voltage to use, check whether the corresponding resistors and capacitors are mounted on the circuit board. Additionally, when using this series of designs, developers must consider electromagnetic compatibility (EMC) design requirements, including ESD and light surge protection.; If the radar requires an enclosure, the enclosure must have good wave-transmitting properties in the 24 GHz band and must not contain metal or materials that shield electromagnetic waves.; When multiple 24 GHz band radars are present, do not install them directly in the line of sight of each others beams; position them as far apart as possible to avoid potential mutual interference.
