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

C/UART

■ 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

C, SPI or UART protocols.

Thus, the board functions as a bridge between a

serial communication based device and a PC.
