[elecena] Adafruit Inductive Charging Set - 3.3V @ 500mA max - zmiany ceny The squarish board with two chips is the transmitter: power it with 9V. The longer board is the output and can be integrated into projects needing wireless power supply.This charging set works by separating a power transformer. An AC waveform generates in one coil and couples with the second. Perfect for projects requiring 3.3V DC output at up to 500mA, it allows for a coil separation of 2 or 3 mm.Optimal for low-power applications, it supports various materials like air, wood, and plastic between coils without affecting efficiency. A mere 40% energy efficiency is typical for this type due to its air-core transformer design, suitable for low-cost toys or simple charging needs.For enhanced versatility, skilled users can adjust the output by modifying the SMT resistor values. This basic yet functional set represents a simple, wireless charging approach.
