Product Introduction:
The product prototype is a wireless power transmission experimental board, using STC main control microcontroller, 7.83Hz Schumann frequency output, equipped with LED flashing with frequency, and 4 mode buttons that can be switched! This product is just a circuit board, without the cost of plastic board shell packaging box, so the cost-effectiveness is very high. Most of the products on the market are classic Schumann wave generators. The circuit prototype is derived from a NE555 Schumann resonance experimental board, with a large number of analog circuits on the periphery. It is not only complex and has poor anti-interference ability, but also easily affected by its own signal crosstalk;
The antenna diagram of this product refers to the SDYG transmitter, which has a wide range of electromagnetic field emission. The originally complex analog circuit is directly written into the STC microprocessor through program code. The highly integrated digital circuit technology optimizes the classic complex analog circuit together, not only supporting one click switching of higher-level power modes, but also further improving its stability and resistance to signal crosstalk.
