Copyright 2023 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved Page 15 of 23 Rd-01 SpecificationV1.1.1 6.3. Precautions for radar installation In motherboard installation position, it is recommended that the following several ways:
As far as possible to ensure that the radar antenna is opposite to test area, and the antenna around open without sunscreen. ensure that the radar installation position is firm, stable, shaking will influence the effect of detection of radar itself. ensure that there won't be on the back of radar object movement or vibration. Due to the penetrating nature of radar waves, the antenna signal back lobe may detect moving objects on the back of the radar. A metal shield or metal backplane can be used to shield the radar back flap to weaken the influence of objects on the back of the radar. The theoretical range accuracy of radar is obtained by special algorithm on the basis of the physical resolution of 0.75m. As target size, condition, different, such as RCS target distance accuracy will fluctuate; And the farthest distances fluctuate a little bit. In order to meet the performance of on-board antenna, antenna surrounding prohibited, metal pieces, far away from the high frequency components. 6.4. Installation environment requirements This product needs to be installed in a suitable environment. If it is used in the following environments, the detection effect will be affected:
Induction of continuous movement in the area of nonhuman objects, such as animals, sustained oscillation of the curtain, is the outlet of the large strain of green plant, etc. induction area exists the strong reflector of large area, strong reflector is of the radar antenna can cause interference. When mounting the wall, need to consider the top of the indoor air conditioning, electric fan etc. External interference factors.

Power Supply Recommended voltage is 3.3V and the peak current is above 500mA. Recommended to use LDO as power supply ; If using DC-DC, it is recommended to control ripple within 30mV. DC - DC power supply circuit suggested the reserved capacitance position, dynamic response can be large changes in load and optimize the output ripple. 3.3V power supply interface increases ESD device is recommended. Figure 14 DC-DC step-down circuit diagram 6.7. GPIO Some IO ports are drawn from the periphery of the module. If necessary, it is recommended to use 10-100 ohm resistors in series on the IO ports. It can suppress overshoot, so make level both sides more smoothly. It helps EMI and ESD. Special IO mouth pull up or down, need to refer to instructions on the use of the specification, here will affect the launch configuration module. Module IO port is 3.3 V if the master IO mouth level does not match with module, need to increase the level conversion circuit. If IO mouth directly connected to the peripheral interface, or terminal, such as row needles, and Suggestions on the IO mouth line near the terminal obligate ESD device Copyright 2023 Shenzhen Ai-Thinker Technology Co., Ltd All Rights Reserved Page 19 of 23 Figure 15 Level switching circuit Rd-01 SpecificationV1.1.1 7. Storage conditions Products sealed in moisture-proof bags should be stored in a non-condensing atmosphere at
<40/90%RH. The module's moisture sensitivity level MSL is level 3. After the vacuum bag is unwrapped, it must be used within 168 hours at 255/60%RH. Otherwise, it needs to be baked before it can be put on line again. 8.
