Zigbee3.0 single fire switch based on EFR32MG (no need to develop single fire wire smart home switch) [Copy link]

Based on the EFR32MG chip, the single-fire switch using the standard Zigbee3.0 can be conveniently and seamlessly connected to each manufacturer's own Zigbee3.0 gateway (providing interface files), cloud services and control terminals (App, mini-programs, compatible with third-party smart speakers), comprehensively solving the industry problem of the long development cycle of Zigbee3.0 single-fire switch hardware and software, and realizing a cost-effective single-fire smart switch solution without development. No circuit design or software design is required, and you only need to adjust and modify the PCBLayout according to your own switch shell. Mature solutions, ready-made circuits, recommended selections and technical support can help you quickly realize the process from engineering prototype to mass production.

Single live wire switch features:

1. Support 15dBm ultra-large transmission power (solves the problem of power consumption and short control distance);

2. Wireless control response time is 250mS, button response time is 200ms (solves the problems of power consumption and slow APP response);

3.Support 1~4-bit single-live-wire intelligent switch;

4. Support 3W-2200W load lamps per channel (no ghost fire, no flickering, low switch heating);

5. Status feedback: Real-time feedback of switch status is clear at a glance.

6. Lamp inspection: Check whether the lamp is installed or damaged.

7. Night indicator: The button has a built-in night indicator light (blue breathing light), so you don’t have to turn on the light in the dark at night; the standby state is indicated by a blue soft LED, which is gentle and not dazzling.

8. No development required: Mature hardware and firmware, no technical development required, can help customers shorten product development cycle, reduce R &D costs, and help customers seize the market faster.

Zigbee3.0 single fire switch mainly consists of two parts: single fire switch base plate + single fire switch control board.

1. Single-fire switch baseplate : It adopts the mature and stable single-fire wire technology solution of Xundi Electronics (specializing in single-fire, doing it more professionally) (cost-effective high-power relay solution, compatible with various lamps, universal load of 3-2200W, no "ghost fire" and no flickering, no contact adhesion, and no circuit burnout). The single-fire switch baseplate is mainly composed of a single-fire wire power supply module XD3390A and a single-fire wire driver module XD-KC024A and other components (the typical power consumption of XD3390A is less than 2.3mW (@Vout1=3.3V with a load of 200uA), and the no-load power consumption is close to "zero" mW.).

The total cost of electronic components for mass production of single-live switch base board PCBA is about 25 yuan (including single-live module, three relays, PCB board, copper terminals, other electronic components, etc.).

2. Single fire switch control board : Its core component is the single fire switch Zigbee3.0 control module, which distinguishes 1, 2, 3, and 4 bits and is used for 1-2-3-4 key single fire smart switches. The single fire switch Zigbee3.0 control module consists of the Zigbee3.0 module and its internal integrated control software (firmware).

2.1) Zigbee3.0 module : uses the EFR32MG chip (powerful and stable performance) from Silicon Labs (also known as "Core Technology), a leading wireless communication chip manufacturer in the industry, and the Zigbee3.0 module is produced by a foundry manufacturer of a Fortune 500 company (ensuring advanced technology and reliable quality).

2.2) Control software (firmware integration): uses the Zigbee3.0 standard protocol stack and mature single-fire switch optimization algorithm, with stable performance and extremely low power consumption.

The ZigBee single live wire switch control module developed using the Silicon Labs EFR32MG21 chip module is an embedded ZigBee wireless communication module that not only supports the latest ZigBee 3.0 standard but is also backward compatible and has industry-leading RF performance.

ZigBee single fire line switch control module series model:
one-position single fire control module: XD3201W
two-position single fire control module: XD3202W
three-position single fire control module: XD3203W
four-position single fire control module: XD3204W

Postscript: The single-fire version of the smart switch based on the EFR32MG21 chip and the standard Zigbee3.0 module is a high-quality single-fire smart switch solution launched on the basis of years of continuous research and development of single-fire core technology and rich experience accumulation. It overcomes many technical difficulties of the existing common single-fire switches on the market and solves the problems of single-fire switches flickering and unstable and easy to burn out.
