LZ5V ELF7.83HZ Schumann Wave Generator PCB Antenna High Efficiency Transmitter Module

Description The product prototype is a wireless transmission experimental board transmitting antenna is completely copied from American S DYG transmitter specially invited senior engineers in Shenzhen to change to STC master single chip 7 83Hz Shuman frequency output equipped with LED blinking at the frequency four modes can be switched by the button This product is just a circuit board no plastic board shell packaging box and other costs so cost effective very high This product completely imitate America S DYG transmitter antenna part drawing electromagnetic field emission is wide and the original complex analog circuit directly through the code written on STC microprocessor highly integrated digital circuit will be sent by the typical complex analog circuit technology optimization not only a key to support more advanced power mode switch further improve its stability resistance to signal cross talk Usage Take out the USB cable connect the round hole end to the circuit board and plug the USB end into the charging case or USB charging head or other USB power supply equipment to work Multiple working modes can be switched through the button standby mode high power transmission mode low power transmission mode lighting mode Specifications Circuit board size 10 x 10cmPower supply interface DC5 5 2 1Supply voltage 5VRated power consumption 1WFrequency 7 83 HzWeight 80gPackage Included 1 x 7 83HZ Schumann Wave Generator1 x 5V DC Power USB Cable
