Transmitter module size: length 17mm width 11mm height 2.5mm
Receiver module size: length 24mm width 10mm height 5.5mm

Transmitting and receiving coil size: outer diameter 38mm inner diameter 28mm thickness 1.3mm

Connection method: 1 pin is connected to the negative pole of the power supply ; 2 pin is connected to the positive pole of the power supply ; 3 and 4 are connected to the external transmitting coil

Transmitter module operating voltage: 5V~12V
Transmitter module operating current: automatically increase or decrease with the receiving load current

Maximum output current of the receiving module: 1A

Transmitting distance: 1~20mm

If the small current works, increase the number of receiving coil turns to increase the transmission distance.

Usage: Connect the DC 5-12V power supply at the transmitting end, then place the two coils close to each other between 1mm and 20mm vertically. Connect the devices that need to be powered, such as LED lights, at the receiving end. The maximum value of the receiver output is 5V/1A.
