2 Overview of the board
The STEVAL-WBC86TX evaluation board is optimized for performance. The board features:
• STWBC86 wireless power transmitter chip with BPP 1.2.4 compatible firmware
• Very few external components, optimized BOM and PCB space
• On-chip high efficiency full bridge inverter
• 32-bit, 64 MHz Arm® Cortex® microcontroller with 8 KB SRAM
• 9-channel, 10-bit A/D converter
• On-chip thermal management and protections
• Foreign object detection (FOD) function
• I2C interface for communication with host system (optional)
• On-board USB-to-I2C converter
• Chip scale package (CSP), ROHS complaint
