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 2 8-pin interface for SPI/I C/UART 6 GPIOs available Opto-isolation on SPI, USART and GPIOs 2 Magnetic isolation for I C 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 2 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.
