STMicroelectronics X-NUCLEO-OUT16A1 Expansion Board is designed for STM32 Nucleo and evaluates the IPS8200HQ octal high-side smart power relay. The STMicroelectronics X-NUCLEO-OUT16A1 interfaces with the microcontroller via STISO620, STISO621, and Arduino R3 connectors. Using jumper settings, choose driving modes (Parallel or SPI) and communication protocols (8- or 16-bits).
