Ujjdwiurgh 0.1Hz~ 99999Hz Frequency Adjustable Wave Generator with Btx V2 V3 Antenna Board Connectable Antenna

Power supply interface: Android interface The digital circuit crystal oscillator frequency reference is more stable and has stronger anti-interference capabilities. It uses low-temperature drift crystal oscillators and high- dedicated chips, which can accurately output frequencies and pure sine waves. Antenna waveform: sine wave waves themselves do not directly act on sound or video products to improve sound quality, but rather on the spatial environment, relaxing the body and mind, improving the body's perception of sound and images, improving the efficiency of human health work, and relieving psychological stress. They also have good effects. Power supply voltage: 5V
