M5Stack CoreMP135 STM32MP135D Linux Controller

Description

The CoreMP135 Linux controller is an integrated industrial host built around the STM32MP135DAE7 processor. This STM32MP135D industrial controller combines a single-core Arm Cortex-A7 CPU up to 1GHz, 4Gbit DDR3L SDRAM, Debian-ready storage, and a compact M5Stack enclosure for embedded Linux control work.

For automation and edge deployment, the CoreMP135 Linux controller provides dual Gigabit Ethernet, CAN-FD, RS485 through PWR485, USB-A, USB-C OTG, HD video output, Grove I2C/UART ports, and M5-Bus expansion. These interfaces make the device a practical industrial IoT gateway for local data collection, cabinet control, network bridging, and machine-side Linux applications.

The STM32MP135D industrial controller also includes a 2.0-inch IPS capacitive touchscreen, 1W speaker, AXP2101 power management, BM8563 RTC, rechargeable battery support, and a DIN-rail base. With a pre-installed microSD card, the CoreMP135 Linux controller can be powered on quickly for HMI, automation, education, and robot motion-control projects.

Features

• Linux-ready control host: the CoreMP135 Linux controller uses STM32MP135DAE7 with a Cortex-A7 processor running up to 1GHz.
• Industrial networking: dual RJ45 Gigabit Ethernet, RS485, CAN-FD, and USB interfaces support gateway and field-control layouts.
• Embedded HMI: a 2.0-inch 240 x 320 IPS capacitive touchscreen and a 1W I2S speaker support local status and operator interaction.
• Expansion ports: M5-Bus, Port.A I2C, Port.C UART, USB-A, USB-C OTG, microSD, and HD video output expand the STM32MP135D industrial controller.
• Power management: AXP2101 PMU, BM8563 RTC, timed wake-up/sleep, rechargeable battery support, and external DC power options support low-power operation.
• Cabinet installation: the DIN-rail base supports rail mounting, wall mounting, and screw-fixed installation for an industrial IoT gateway.
• Development workflow: the CoreMP135 Linux controller supports UiFlow2 and Linux development resources for rapid prototyping.

Specifications

Linux and Bus Power Notes

The STM32MP135D industrial controller ships with a microSD card pre-installed in the device, so the Linux system can start without a separate storage setup. For M5-Bus power control, the official documentation notes that BUS_OUT_EN can be set through Linux GPIO when 5V output is required.

Interface Planning

The CoreMP135 Linux controller exposes dual Ethernet, RS485, CAN-FD, M5-Bus, Port.A I2C, Port.C UART, USB, microSD, and HD video. This interface mix is what makes the STM32MP135D industrial controller suitable as an industrial IoT gateway when a project needs both network connectivity and field-device communication. In cabinet projects, the STM32MP135D industrial controller can act as an industrial IoT gateway close to sensors, machines, and operator panels.

Installation Notes

The bottom DIN-rail mounting plate helps the CoreMP135 Linux controller fit control cabinets and industrial enclosures. The same base can support wall mounting or screw-fixed installation when rail mounting is not available. This makes the industrial IoT gateway easier to place near machine networks, while the STM32MP135D industrial controller stays accessible for maintenance.
