1. Intelligent routing control unit: using Microchip's low-pin, low-power 8-bit MCU with high cost performance as the main control.
2. Bluetooth: Bluetooth dual-mode module is used, which can support BT4.0 (BLE) and BT3.0 + EDR. There is also a BM70 BLE module with a 55nm process and lower power consumption. In addition, there is a Bluetooth SOC chip that supports BT4.2 or Mesh in the Bluetooth light.
3. Wi-Fi: MTK Wi-Fi module with stable transmission data.
4. Smoke detector: The main control adopts RE46C191 / RE46C190, the biggest feature of this IC is to support 3V power supply, support CE, internal integrated DC2DC function, and can realize equipment cascade and status output, patrol inspection and other time periods adjustable.
5. Smart socket / power supply part: adopts power monitoring MCP39F511 with calculation and energy accumulation function, this IC provides all commonly used standard power calculation and some advanced functions, and integrates the input and output of active energy accumulation, four-quadrant reactive energy accumulation, Zero-crossing detection and dedicated PWM output are integrated on the chip, and can also measure active power, reactive power 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 wearable applications.
