Description
The STM32MP257F-DK Discovery kit is designed as a complete demonstration and development platform for the STMicroelectronics STM32MP257FAK3 based on the Arm® Cortex® A35 and M33.The product leverages the capabilities of STM32MP2 series microprocessors to allow users to develop applications using STM32 MPU OpenSTLinux Distribution software for the main processor (Arm® dual core Cortex®‑A35) and STM32CubeMP2 software for the coprocessor (Arm® Cortex®‑M33).The product includes an ST-LINK embedded debug tool, LEDs, push-buttons, 1 Gbit/s Ethernet, one USB3 USB Type-C® PD, two stacked USB 2.0 HS Type-A, one LCD LVDS display connector, one HDMI connector, one camera connector, microSD™ card, Wi‑Fi® 802.11b/g/n, Bluetooth® Low Energy v4.1, and eMMC. To expand the functionality of STM32MP257F-DK, one GPIO expansion connector is also available for Raspberry Pi® shields.
