1. Integrated with a power switch, it is more convenient to turn on and off the power, eliminating the need to plug and unplug the charging port every time it is used

2. Dual power port design, no longer troubled by incorrect data cable interfaces

3. Unique addition of TVS static protection and short circuit protection on the board, safe and reliable

4. Using imported chips, the frequency and pulse width are more stable

5. Added a power switch, turning it to the ON position to turn on the power, and turning it to the OFF position to turn off the power

Product Introduction

Schumann wave generator

Power supply voltage: 5V

1. Using imported chips, the frequency and pulse width are more stable

2. Double layer FR-4 1.2T-PCB board, PCB board quality is stable and more reliable

3. Increase the transmission coil, enhance the 28 coil transmission coil, and expand the transmission range

4. The board supports two power interfaces, TYPE C (supporting forward and reverse insertion) and USB Micro, so you don't have to worry about finding different charging cables anymore

5. Unique protection circuit, adding high-power TVS electrostatic protection tube to prevent damage to the chip from static electricity in hands and air.

6. Add PPTC self recovery fuses to prevent the complete disconnection of power supply to the board after a short circuit occurs. When the short circuit is resolved, the fuse automatically returns to normal, making it safer and more reassuring to use.

7. Added a power switch, turning it to the ON position to turn on the power, and turning it to the OFF position to turn off the power.
