Features1. 4-channel independent control for seamless switching between car, boat, and tank scenarios2. 2.4G anti-interference frequency band ensures stable transmission without signal loss3. 10A high-current drive effortlessly powers high-torque servos4. DC 3V-4.5V safe operation compatible with mainstream batteries5. Stable performance up to 50m in open areas, reliable control in complex environmentsParameterTransmitter Board Voltage: DC 3-4.5VReceiver Board Voltage: DC 3-12VDrive Current per Channel: 10AFrequency: 2.4G (Multiple sets can operate simultaneously without frequency interference)Remote Control Range: Approximately 50 metersProduct DescriptionSuitable for standard remote-controlled toy cars, boats, tanks, or other small electric toys. The left two buttons on the transmitter control the forward/reverse rotation of one motor on the receiver board. The right two buttons control the forward/reverse rotation of the other motor on the receiver board. The receiver board features reverse polarity protection. The drive chip includes overheat, overcurrent, and short-circuit protection. Final note: Brushed motors have no polarity distinction. If the control direction is incorrect, simply swap the two wires connected to the motor on the receiver board.Frequency Pairing MethodAutomatic pairing: First power the transmitter board—the LED will flash. Then power the receiver board; when the transmitter board's indicator light turns off, pairing is successful.Important NotesDo not extend or modify the antennas on the transmitter or receiver boards, as this may reduce control range or cause malfunction. For optimal range, keep the antennas straight and perpendicular to the ground plane during operation.Package includeRemote Control Board1Receiver Board1Battery Box*1
