SMFEM01 SMBTN01 is a mini size 7.83Hz Pure Sine Wave Schumann Resonances designed and produced by eletechsup. SMFEM01 is the basic version, it uses a TYPE-C power supply; SMBTN01 is the battery version, it uses a LI-PO battery with PH2.0. Both of them can use the same shell.
Note: Batteries need to be prepared by yourself, and the shell needs to be purchased separately
Please contact us for more information!
Version A (Basic Version)
Supply voltage: DC 5V
Working current: 3MA
Waveform: Sine wave(can't output Other waves)
Power supply interface: TYPE-C
Frequency: 7.83Hz sine wave
Signal voltage amplitude: 3.3V
PCB Board Size: 76*57*5MM
Weight : 15g
How to use: Connect the DC 5V power supply to the TYPC-C interface.
Version B (Battery Version)
Input voltage: DC 5V(Type-c)
Battery voltage:4.2V/3.7V
Working current: 0.4MA
Waveform: Sine wave(can't output Other waves)
Power supply interface: TYPE-C
Frequency: 7.83Hz sine wave
Signal voltage amplitude: 3.3V
PCB Board Size: 76*57*5MM
Weight : 16g
how to use:
1 Insert a lithium battery with a PH2.0 interface into the battery port (you need to bring your own battery)
2 Turn the switch to the ON position
3 Use the TYEP-C power supply to charge the battery
4 After fully charged, unplug the TYPE-C power supply.
Note:
1 Version B requires batteries to work.
2 It is recommended to use 1000-2000mAh LIPO batteries with PH2.0 interface
3 Working current 0.4MA, theoretically 1000mAh can last 100 days
4 Pay attention to the positive and negative poles of the battery
Normally, the product will work as long as you provide power
(The battery version needs to connect the battery and turn the switch to ON)
But if you want to see the waveform:
Please use the oscilloscope probe to connect the two ends of the D2 diode for measurement.
