Feature:
KQ-130F is a single 9-pin small-sized high-performance zero-crossing carrier data transceiver module. Specially designed and developed cost-effective carrier modules designed for reliable transmission of data under 220V AC, strong interference, strong attenuation, and long-distance requirements. The KQ-130F carrier module includes many complex peripheral circuits such as carrier drive, coupling, filtering, and lightning protection. The user only needs to provide a single 5V power supply. After the two signal lines (TX, RX) are connected to the MCU, the two AC terminals of the module are directly connected to 220V (without the FireWire and Neutral) to realize the communication via the power carrier like 485. Transparent way to send and receive data. KQ-130F carrier module is suitable for meter reading, street lamp, smart home, fire control, building control and other application fields that need power line to transmit data. Transmission distance up to 1.5Km.
Zero point modulation and demodulation based carrier module. Anti-interference ability, the transmission distance is much better than the so-called zero-crossing module in many markets.
One, KQ-130F series performance:
1. Integrate the KQ-330F module and peripheral circuit carrier board, without the need for other coupling components, directly connected to 220V AC. Appearance size is 53 × 38 × 17 mm (L × D × H), single row pin out (see below) 1, 2 foot 220V AC power supply without direction (1 foot, 2 foot spacing 2X0.1 inches), 2 feet, 3 feet, 1.1 inches apart, 0.1 inches apart.
2. Operating frequency 120 ~ 135KHZ, interface baud rate 9600bps. The actual baud rate is 100bps.
3. Maximum length of one frame continuous transmission ≤ 252 bytes, one frame continuous transmission length from 1 to 252 defined by the user, the module will not send extra data
4.Power supply: DC +5V When receiving: ≤11mA When sending ≤230mA
5.Power frequency insulation withstand voltage: no breakdown at 3000V 1min between AC and GND, no leakage current.
6.Anti-lightning: TVS tube protection within the board, from PCB board wiring to component selection are based on wide temperature, high pressure, high pressure impact design.

1P-AC: FireWire (or Neutral) with 220V AC Voltage
2P-AC: Zero line (or FireWire) for 220V AC voltage
3P-+5V: +5V transmit power (210mA), if single-receive data can be left floating to reduce power consumption
4P—GND: Digital Circuit Ground
5P-+5V: +5V operating power supply 11mA, minimum operating voltage up to 3.3V but not recommended
6P-RX: TTL level, carrier data input, then TXD
7P-TX: TTL level, carrier data out, then MCU's RXD
8P_MODE: Mode selection, float or connect 5V to high level, ground to low level
9P-NC/RST : Reset pin (active low) Used when frequently switching modes during operation. Needed this function, the pin should be left unconnected
