X-STM32MP-IGTW1

X-STM32MP-IGTW1 is a STM32MP MPU expansion board for industrial IoT gateway applications, featuring a range of wired communication interfaces. The X-STM32MP-IGTW1 operates with a power supply between 12 to 24V and interfaces with the STM32MP microprocessor via a 40-pin GPIO connector using I2C, UART, FDCAN, and GPIO connections. The board is compatible with the STM32MP257F-DK connector layout. The ST4E1240 is a high-speed RS-485 transceiver supporting data rates up to 20Mbps. It features low-power consumption, integrated ESD protection, and fail-safe mechanisms for reliable communication in industrial applications. The ST3232C is a dual RS-232 transceiver operating from 3.0 to 5.5V, supporting data rates up to 400kbps. It features integrated charge pump capacitors and has low-power consumption (1µA in shutdown). A further serial communication capability is given by a high-speed CAN transceiver designed for reliable communication in automotive and industrial applications.
