CoreMP135
Description
CoreMP135 is an integrated Linux industrial control host based on the STM32MP135DAE7 chip. It features a single-core Arm Cortex-A7 processor with a frequency of up to 1GHz and is equipped with 4Gb DDR3L SDRAM for running memory. The device boasts a rich array of functional interfaces: it has 2 GbE ports, 1 HD video output, 2 USB 2.0-A ports, 1 USB-C port (supporting OTG and power supply), a MicroSD card slot, 2 CAN FD interfaces, and 1 PWR485 interface (9~24V power input + RS485), along with 2 Grove (I2C & UART) interfaces. In terms of human-machine interaction, it features a 2.0-inch IPS capacitive touch screen and a 1W speaker (16 bits I2S driven). The device is designed for low power consumption, utilizing an AXP2101 power management chip and an integrated RTC (BM8563) for scheduled wake-up and sleep functions, and supports a rechargeable battery. It includes a DC power socket supporting an external DC12V@2A power supply. The host comes with a MicroSD card preloaded with Debian system, ready to use upon booting. Suitable for various installation scenarios, the device’s bottom is equipped with a DIN rail base plate for easy wall mounting and screw fixing. It is applicable in advanced industrial automation, smart home and multimedia entertainment devices, industrial IoT edge gateways, and as a central hub for robot motion control.
