Large Power 4km Wireless RF Remote Transmitter Module Kit for Arduino ARM

Large Power 4km Wireless RF Remote Transmitter Module Kit for Arduino ARM

Instructions for use:

• The antenna has a great influence on the receiving effect of the module. It is best to connect the antenna with 1/4 wavelength, generally using a 50-ohm single-core wire.

• Application scenarios: wireless system, anti-theft alarm, wireless data transmission, automation, data collection, etc.

• The antenna of the transmitting module is far away from the metal shield and is installed vertically in the air to avoid interference.

• The connection of the module should be as short as possible, and the high-frequency emission part should be avoided.

• The module uses DC 9V power supply, the power supply can provide 800mA current in an instant, and the module should not be in the transmitting state for a long time. It is recommended that each transmission time should not exceed 10s

• The adjustable capacitor on the PCB has been glued and fixed and cannot be changed, otherwise, it will change the frequency or reduce the power
