Applications
The bq51013AEVM-764 evaluation module (EVM) demonstrates the receiver portion of the bqTESLA™
wireless power system. This receiver EVM is a complete receiver-side solution that produces 5 V out at up
to 1 A when coupled with the bqTESLA™ transmitter. The bq51013AEVM-764 device shown on this EVM
along with external components that support the device for a complete solution.

Modifications
See the data sheet (
) when changing components. To aid in such customization of the EVM, the
board was designed with devices having 0603 or larger footprints. A real implementation likely occupies
less total board space.
