STEVAL-PCC009V4

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/I2C/UART ■ 6 GPIOs available ■ Opto-isolation on SPI, USART and GPIOs ■ Magnetic isolation for I2C ■ RoHS compliant STEVAL-PCC009V4 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 I2C, SPI or UART protocols. Thus, the board functions as a bridge between a serial communication based device and a PC.
