Description
STEVAL-ISB038V1T is the wireless battery
charger transmitter module in the STEVAL-
ISB038V1 Reference Design Kit.
The STEVAL-ISB038V1 is a wireless battery
charger evaluation kit designed for ultra-compact
battery operated devices such as wearable gear,
smartwatches, Internet Of Things sensors,
medical devices, etc.
The kit supports wireless power transfer of 1 Watt
over an 11 mm coil on the receiver side and 20
mm on transmitter side.
The kit configuration delivers 1 Watt of power at
the receiver side.
While the Kit is configured to support low power
(1 W) applications, it can support up to 3 W
applications with wider coils or by switching to
full-bridge configuration on the transmitters.
The STWBC-WA transmitter is based on a cost-
effective half bridge topology (full-bridge optional)
offering the flexibility of a powerful software API
allowing LED and GPIO control, as well as
adding external interfaces via I²C and UART
communication ports.
