STMicroelectronics STM32MP157D-EV1 Evaluation Board is designed to evaluate the features of 800MHz Arm-based dual Cortex®-A7 32-bits and Cortex®-M4 32-bits STM32MP1 MPUs. This board with STM32MP1 MPUs helps to develop the applications using STM32 MPU OpenSTLinux distribution software for the main-processor and STM32CubeMP1 software for the co-processor. The STM32MP157D-EV1 board includes ST-LINK embedded debug tool, LEDs, push-buttons, joystick, 1-Gbps Ethernet, CAN FD, USB OTG Micro-AB connector, and four USB Host Type-A connectors. This board also includes an LCD display with a touch panel, camera, stereo headset jack with analog microphone input, one SPDIF Rx/Tx, and four digital-microphones. To expand the functionality of the STM32MP157D-EV1 evaluation board, two GPIO expansion connectors are available for motor control and Raspberry Pi shields.
