Key Benefits
Mainlined OpenSTLinux Distribution
One OpenSTLinux Software compatible with STM32MPU Family. OpenSTLinux expansion packages can be applied on the top to enable the use of additional components.
DDR3L support for market advantage
On top of the DDR4/LPDDR4, the STM32MP2 Series supports DDR3L memory, enabling you to maintain competitive pricing and secure supply amid DDR4/LPDDR4 shortages and price surges observed since middle of 2025.
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.
