1. Intelligent routing control unit: Using Microchip's low-pin, low-power, high-performance 8-bit MCU as the master.
2. Bluetooth: Bluetooth dual-mode module supports BT4.0 (BLE) and BT3.0+EDR. There is also a 55nm process, lower power consumption of the BM70 BLE module, and a Bluetooth SOC chip that supports BT4.2 or Mesh in the Bluetooth light.
3. Wi-Fi: The MTK Wi-Fi module with stable transmission data.
4. Smoke detector: The main control adopts RE46C191/RE46C190. The biggest feature of this IC is that it supports 3V power supply, supports CE, integrates DC2DC function internally, and can realize device cascade and status output, and the time period such as inspection can be adjusted.
5. Smart Socket/Power Part: Power monitoring MCP39F511 with calculation and energy accumulation, this IC provides all the usual standard power calculations and some advanced functions, and integrates the input and output of active energy, four-quadrant reactive energy accumulation, Both zero-crossing detection and dedicated PWM outputs are integrated on the chip and measure active, reactive, and apparent power, RMS current and RMS voltage, line frequency, and power factor.
6. Low-Power Static LDO: The MCP1702 has a quiescent current of only 2uA, making it ideal for IoT products and portable devices such as wearables.

Metal Push Button Switch
Yeswitch Metal Push Button Switches, also call Push Button Switch , is the most popular switches around the Switch Industry. This Illuminated Push Button Switch can be found on valuable machine and public ticket dispenser applications, along with other industrial type applications that require vandal resistance in a public setting
Our Push Button Switches are available in 19mm, 22mm and 25mm installation size . We have Momentary Push Button Switch and self -lock metal switches, which mechanical life could respectively reach 1,000,000 and 500,000 cycles. This metal switches are normally made of stainless, brass with mirror chrome plated, brass with nickel plated, AL alloy and other Industrial materials.
On the items of button type, We also offer flat, high and round with LED light for our customers to choose from. Meanwhile, this metal switches could equip with LED light, which have Various color . What worthy to be mentioned is that we could offer double color LED light, like red&green,red&and blue, red& and yellow,etc. In addition,the light type could be without LED,ring(fixed),sport, ring(moveable).
The advantage of this switches is that its water resistance to IP67 ratings, and have TUV, European and American environmental protection RoHS and lead-free environmental protection certification . Furthermost, its operation temperature could range from -20-85, which indicates that this metal switch could work in the very hash environment with .
