Description
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.
