The bqTESLA™ wireless power transmitter evaluation module from Texas Instruments is a high-
performance, easy-to-use development module for the design of wireless power solutions. The bq50002A
evaluation module (EVM) provides all the basic functions of a Qi-compliant, wireless charger pad. The 5-V
input, single coil transmitter enables designers to speed the development of their end-applications. The
EVM supports both the Qi WPC 1.0, WPC 1.1, and WPC 1.2 receivers and will support output power up to
5 W.
