STEVAL-ISB038V1 (STMICROELECTRONICS)

The STEVAL-ISB038V1 is a 1W wearable wireless power system based on STWBC-WA and STWLC04 modules. This wireless battery charger evaluation kit is designed for ultra compact battery operated devices such as wearable gear, smart watches and IoT sensors. The kit supports wireless power transfer of 1W over an 11mm coil on receiver side and 20mm on transmitter side. The kit configuration delivers 1W of power at receiver side. While kit is configured to support low power (1W) applications & can support up to 3W applications with wider coils or by switching to full bridge configuration on transmitters. The STWBC-WA transmitter offers flexibility in terms of offering a powerful software API which allows to modifying behaviour of LED and GPIOs as well as adding external interfaces via I2C and UART ports. The STWLC04 is focused on 1W protocol based on Qi.Digital control and precise analogue control loops assure stable operation. I2C interface allows many parameters to be customized in device
