Wireless Power Transfer Coil Kit for DIY Projects and Prototyping
Transmitter and Receiver Coil Set for Inductive Charging and Wireless Energy Transmission
A Wireless Power Transfer (WPT) coil kit contains the essential transmitter and receiver coils needed to build a wireless power system. This is the fundamental hardware for projects like contactless battery charging for wearables, smartphones, smartwatches, or for powering low-current devices without physical connectors [citation:12][citation:4][citation:9]. The principle is based on inductive coupling, where an alternating current in the transmitter coil creates a magnetic field that induces a voltage in a nearby receiver coil [citation:3][citation:8].
EasytoUse Module Simple setup with a transmitter (912V input) and receiver (5V output) for quick prototyping.
Wide Application Range - Suitable for wireless charging of mobile phones, smartwatches, and other small electronics [citation:4][citation:5].
The transmitter coil typically requires a 912V DC power supply, and the receiver board provides a regulated 5V output capable of 350450mA [citation:4].
Use with an Arduino Uno or similar MCU to control the frequency and create flashing or sequenced effects [citation:3].
Key Features
Transmitter and Receiver included - Complete set ready for integration into DIY projects.
Compact form factor - Small PCB and coils suitable for tight spaces [citation:4].
Adjustable distance Output current varies inversely with coil distance; works within 36mm [citation:4].
= Common Applications =
- Smartphone and Wearable Charging - Add wireless charging capabilities to custom enclosures or devices [citation:5][citation:12].
- DIY Lighting Displays Transmit power to multiple, selfcontained wireless LEDs that can be controlled individually [citation:3].
- Sealed and Waterproof Devices - Eliminate the need for exposed charging contacts in outdoor or industrial products [citation:4].
PlugandPlay - Straightforward connection and testing for a quick project start.
Safe and Convenient - No exposed conductors, reducing the risk of short circuits and corrosion.
√ Compatible with popular microcontroller boards like Arduino, STM32, and ESP8266.
√ Widely used in DIY, educational, and rapid prototyping settings.
√ Easy integration with battery charging modules for portable projects.
Troubleshooting
Low output current or no power:
- The distance between coils is too great; for 5V output, position coils 3-6mm apart for best efficiency [citation:4].
- Verify the input voltage to the transmitter is within the correct 9-12V DC range [citation:4].
System not working:
- Use a multimeter to check that the transmitter is drawing power and that the receiver output is within the expected range.
- Ensure proper polarity and secure connections on both boards.
