Scheme introduction
Single fire WIFI switch PCBA scheme without parallel connection capacitor (2-2200W),
WiFi is the most widely used wireless communication technology at present. WiFi can be used online only by connecting to the WiFi router at home. WiFi smart switch is an application of communication technology based on WiFi, which can communicate directly with mobile phones without a gateway. Mobile phones have more direct and flexible control over smart switches (lighting systems), and the entire network has less data transmission delay. This is an advantage that ZigBee and other wireless technologies do not have.
For a long time in the industry, people have realized single fire switch communication through ZIGBEE and Bluetooth. Since ZIGBEE and Bluetooth need to be configured with gateway and MESH, the use cost of end users has increased. Based on the advantages of WIFI, some people have already made WiFi single fire switches. However, the existing single fire WIFI switches sold on the market need to connect capacitors at both ends of the lamps in parallel, resulting in poor customer experience. In order to meet the actual needs of the market and customers, through the continuous efforts of the technical team, we have finally successfully developed a new generation of WiFi single live wire intelligent switch without parallel connection of capacitors and other "anti flash" devices on the lamps. The scheme adopts 7-400V ultra wide voltage 200mA large current micro power consumption single live wire power supply module XD3390A, which solves the problem of insufficient power supply for single fire switch circuit, realizes stable single live wire power supply, provides WIFI communication and maintains long connection, and increases reliability.
