The P9038-R-EVK is a turnkey 5 Watt, Qi-compliant wireless power transmitter reference kit for fast prototyping and design integration. The kit consists of an easy-to-use reference board and comprehensive support collateral that significantly eases design-in effort and minimizes time-to-market. 

An associated layout module enables direct instantiation on to a system board, while an optimized and fully-tested Bill-of-Materials (BOM) takes the guess-work out of component selection. The P9038-based solution is well-suited for a wide range of applications, including PC peripherals, furniture, medical devices, and other portable devices still hindered by traditional contact-based charging bases or cables. 

Need a wireless power receiver too? See the P9025AC-R-EVK.
