1. The carrier board that integrates the KQ-330F module and peripheral circuits does not require other coupling components, and can be directly connected to 220V AC power. The external dimension is 53x38x17 mm (LxDxH), and the single row of pins leads out. 1 and 2 pins are connected to 220V AC power supply without direction (1 pin, 2 pin spacing 2X0.1 inches), 2 feet and 3 feet are 1.1 inches apart, and the rest of the feet are 0.1 inches apart. 2. The working frequency is 120~135KHZ, and the interface baud rate is 9600bps. The actual baud rate is 100bps. 3. The maximum length of one frame of continuous mission is ≤252 bytes, the length of one frame of continuous mission is defined by the user from 1 to 252, and the module not send redundant data 4. Receiving sensitivity ≤1mV 5. Out-of-band rejection capability ≥ 60 dB 6. Bandwidth ≤10 KHZ 7. Insulation resistance 500V ≥500MΩ 8. Power supply: DC +5V when receiving: ≤11mA when sending ≤230mA 9. Power frequency insulation withstand voltage: 3000V 1min test between AC and GND has no breakdown and no leakage current. 10. Anti- strike: tube protection inside the board, from PCB board wiring material selection to component material selection, are designed according to wide temperature, high pressure resistance, and high pressure shock resistance. 11. Working temperature: -25℃~70℃ Humidity≤90% KQ-130F power carrier module does not need any peripheral devices, as long as it provides a 5V power supply, it can be used. The mission power supply is pin. If the user needs bidirectional mission, two 5V pins can be connected in parallel. All modules of our company support point-to-point, point-to-multipoint networking communication mode, and control of multipoint data through polling. color:As shown Material:PCB Package Contents: 1 x KQ-330F module Only the above package content, other products are not inc
