[Introduction]：The ECK10-131A2M2M-I is a compact industrial-grade Linux System-on-Module (SoM) built around STMicroelectronics’ STM32MP131 MPU. Integrating the power supply circuit, DDR3L memory, NAND FLASH, and Gigabit Ethernet PHY on a single 38×32mm stamp-hole board, it dramatically reduces baseboard design complexity and time-to-market. Designed for industrial IoT edge computing, HMI, and embedded Linux applications, it delivers reliable performance from -40℃ to +85℃. Available as a standalone core board or bundled with the ECA10-7LCD24R1006CT-C 7-inch LCD display kit.
* CAN FD and camera interface supported on STM32MP135 variant only.

Frequently Asked Questions
Q: What Linux distributions are supported on the ECK10-131A2M2M-I?
A: The ECK10-131A2M2M-I supports ST’s official OpenSTLinux distribution, as well as Buildroot and Yocto Project-based custom Linux builds. Ebyte provides a BSP (Board Support Package) including kernel, device tree, and drivers for all on-board peripherals. U-Boot bootloader is supported for NAND FLASH and SD card boot.
Q: What is the difference between the STM32MP131 and STM32MP135 variants?
A: Both share the same ARM Cortex-A7 core at 650MHz. The STM32MP135 adds a parallel display interface (up to WXGA 1366×768), a digital camera input, and 2× CAN FD interfaces — making it suitable for HMI and vision applications. The STM32MP131 is optimized for cost-sensitive headless IoT and communication gateway designs.
Q: How is the ECK10-131A2M2M-I connected to a custom baseboard?
A: The SoM uses plated stamp-holes (half-holes) with 0.8mm pitch for SMD reflow soldering directly onto a custom baseboard. This eliminates connectors, reduces height, and improves vibration resistance. Ebyte provides reference schematics, PCB footprint libraries, and baseboard design guidelines to accelerate hardware development.
Q: What power supply does the ECK10-131A2M2M-I require?
A: The SoM requires a 5V DC input on the baseboard. The on-board PMIC generates all internal voltages (1.8V core, DDR, I/O). Additionally, the SoM provides 3.3V (max 1A) and two software-adjustable LDO outputs (1.7–3.0V, max 350mA each) for powering baseboard peripherals.
Q: Is the ECK10-131A2M2M-I suitable for long-term production use?
A: Yes. The ECK10-131A2M2M-I is designed for industrial-grade long-term deployment with a -40℃ to +85℃ operating range, industrial-grade component selection, and Ebyte’s commitment to long-term supply continuity. The STM32MP13 series from STMicroelectronics has a 10+ year longevity guarantee, making it suitable for embedded products requiring multi-year production stability.
