STMicroelectronics STM32MP257F-EV1 Evaluation Board

STMicroelectronics STM32MP257F-EV1 Evaluation Board is a development platform for the STM32MP257FAI3, which features Arm® Cortex®-A35 and M33 cores. It supports STM32 MPU OpenSTLinux distribution software for the main processor (dual-core Cortex-A35) and STM32CubeMP2 software for the coprocessor (Cortex-M33). The STMicroelectronics STM32MP257F-EV1 includes an ST-LINK embedded debug tool, LEDs, push-buttons, three 1Gbit/s Ethernet ports, two CAN FD ports, and a USB Type-C™ DRD connector. Additionally, the board has a GPIO expansion connector compatible with Raspberry Pi® shields and a mikroBUS™ expansion connector for further functionality.
