## Description

This inductive charging set provides wireless power transfer using a split-transformer design. The transmitter coil is powered with 9–12 V DC, and the receiver coil outputs 3.3 V DC — no direct wire connection between the two halves is needed. Any non-ferrous, non-conductive material (air, wood, plastic, glass, leather, paper) can be placed between the coils. Key Features Wireless Power Transfer – Inductive coupling via air-core transformer 3.3 V DC Output – Regulated output from the receiver board Up to 500 mA – At 2–3 mm coil separation Two-Board Set – Separate transmitter and receiver modules Adjustable Output – Feedback resistor divider on the receiver can be modified for different output voltages (advanced users) Specifications Input Voltage – 9–12 V DC (transmitter) Output Voltage – 3.3 V DC (receiver) Max Output Current – 500 mA (at 2–3 mm separation) Quiescent Current – ~70 mA (transmitter, with no receiver present) Efficiency – ~40% Distance vs Current 2–3 mm – Up to 500 mA ~7 mm – Up to 100–200 mA ~12.5 mm – Up to 10 mA Tip: Align the coils as parallel and co-axial as possible for best power transfer efficiency. Package Contents 1× Transmitter board (input, 9–12 V DC) 1× Receiver board (output, 3.3 V DC) Ideal For Wireless charging projects Sealed enclosure power delivery Wearable electronics Prototyping contactless power systems
