Product Description

Schumann wave itself does not directly act on the sound or video products to improve the sound quality, but acts on the space environment, can relax the human body and mind, improve the human body's ability to perceive the sound and image, improve the human body's health and work efficiency, and alleviate psychological stress. The effect is better. This product can not only output 7.830Hz Schumann wave, but also can be adjusted in the range of 0.001Hz ~ 200KHz frequency, digital circuit crystal oscillator frequency reference, more stable.

Features：

1. Using DDS algorithm, the frequency step value can be up to 0.001HZ, good frequency stability.
2. This product can not only output 7.830Hz Schumann wave, but also increase the programmable frequency modulation technology, can be adjusted in the range of 0.001Hz ~ 200KHz frequency (can also be used as an ordinary programmable digital signal generator).
3. Digital crystal oscillator frequency reference, more stable, more anti-interference;
4. Power supply interface using DC5.5*2.1 interface, easy to use, USB terminal can be inserted into the power supply or USB charging head or other USB power supply device work.

Instructions for use：

Take out the USB cable that comes with the product, connect the round hole end with the circuit board, and plug the USB end into the power bank or USB charging head or other USB powered devices to work.
