Design guidance 3.1. Application guidance circuit LS-3202 V1.0 Fig. 11 Application Guidance Circuit If the IO port is used as PWM, it is recommended to reserve a pull-down resistor of 4.7K at the periphery of the module. Especially the application of light control, to prevent the flashing phenomenon at the moment of power-on start-up. 8/NC pin, which cannot be used by default. 3.2. Recommended PCB package size Figure 12 Recommended PCB package size LS-3202 V1.0 3.3. Antenna layout requirements In the installation position on the motherboard, the following two methods are recommended:

Scheme 1: Place the module on the edge of the motherboard, and the antenna area extends out of the edge of the motherboard. Scheme 2: Put the module on the edge of the motherboard, and the edge of the motherboard hollows out an area at the antenna position. In order to meet the performance of onboard antenna, it is forbidden to place metal parts around the antenna, away from high-frequency devices. Fig. 13 Schematic diagram of antenna layout 3.4. supply electricity Recommended voltage is 3.3V, and peak current is above 500mA. It is recommended to use LDO for power supply; If DC-DC is used, it is recommended to control the ripple within 30mV. DC-DC power supply circuit suggests to reserve the position of dynamic response capacitor, which can optimize the output ripple when the load changes greatly. It is suggested to add ESD devices to the 3.3V power interface. LS-3202 V1.0 Fig. 14 DC-DC step-down circuit diagram 4. Storage condition Products sealed in moisture-proof bags should be stored in non-condensing atmospheric environment of < 40/90%RH. The moisture sensitivity level MSL of the module is level 3. After the vacuum bag is unpacked, it must be used within 168 hours at 25 5/60% RH, otherwise it will need to be baked before it can be put on the line again. LS-3202 V1.0 2.2 List of applicable FCC rules FCC Part 15.247 2.6 RF exposure considerations This equipment complies with the FCC RF radiation exposure limits set forth for an uncontrolled environment.
