Reference Design Peripheral MCU WIFI MODULE If the peripheral MCU uses power source of 5V,it needs to add a level switching circuit in the connection of the serial port and the related circuit.
8. AntennaCharacteristics 8.1 Antenna Selection The WT1SBSL supports on-board PCB printed antenna.When the Operating Frequencyis between 2.4G~2.5GHz, S11 of antenna port is less than-10dB and peak gainis about 1. 2dBi. Figure 7. Antenna radiation pattern simulation Figure 8. Antenna port S11simulation curve In practical use, 3329-P is welded on user’s boardand value of S11 has some changes. 13www.ibroadlink.
8.2 Minimizing Radio Interference When integrating the Wi-Fi module with on board PCB printed antenna, make sure the three points below: 1. The area under the antenna end of the module should be keep clear of metallic components, connectors, vias, traces and other materials that can interfere with the radio signal. 2. The area around the antenna end the module protrudes at least 10mm from the mother board PCB and any metal enclosure. 3.
