STEVAL-PCC009V4
Opto-isolated universal USB to serial bridge demonstration board
for motor control applications
Data brief
Features
■ STM32-based demonstration board used as
the interface between the PC and motor control
systems
■ 8-pin interface for SPI/I
■ 6 GPIOs available
■ Opto-isolation on SPI, USART and GPIOs
■ Magnetic isolation for I
■ RoHS compliant
Description
The STEVAL-PCC009V4 demonstration board
implements a universal USB on the serial isolated
interface communication. It is useful in all
applications which need safe connection from PC
to the application boards.

The STEVAL-PCC009V4 has a 16-pin
communication interface which allows connecting
a device that uses I
2
C, SPI or UART protocols.
Thus, the board functions as a bridge between a
serial communication based device and a PC.
