Beschreibung
The STEVAL-ISB039V1T is a wireless power transmitter based on the STM32F0 microcontroller and primarily designed for small systems requiring easy recharging up to 1 W; this solution can be adjusted up to 2.5 W.The wireless power transmitter consistes of a power conversion unit which generates the alternating electromagnetic field transmitted between two planar coils.The built-in USB connector supplies the wireless power transmitter and the SWD debugger connector allows the monitoring of system parameters such as battery charging level, power transmitted, efficiency, working frequency and power receiver identification.The firmware is a single STM32CubeMX platform-independent library providing a simple and easy to customize solution for the design of wireless power transmitters with proprietary features.
