Product overview
Description
The STEVAL-ISB042V1 is a 15-watt Qi and 5-watt Airfuel inductive (former PMA) wireless power receiver evaluation board based on the STWLC33 wireless power receiver solution for the WPC/Airfuel mobile device with dual mode coil.
The board lets you evaluate the STWLC33 capabilities as a Qi/Airfuel inductive receiver as well as its ability to power another Qi receiver.
The solution is certified in accordance with the extended power profile Qi v1.2 and Airfuel SR1 standard.
The STWLC33 IC is powered by a dual mode Rx coil attached to a 1.5 mm thick plastic fixture.
The STWLC firmware offers users the flexibility to modify parameters and settings to ensure proper integration of the STWLC33 device with the final application.
The layout is based on a cost-effective 4-layer PCB.
