SKU:K135

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.

MBUS Power

CoreMP135 MBUS power bus input and output control:
Refer to the schematic diagram and set BUS_OUT_EN to low level, then the bus 5V is in input mode, and high level, then the bus 5V is in output mode. You can use the following command to turn on the downward output:
echo 131 > /sys/class/gpio/export && echo out > /sys/class/gpio/PI3/direction 
echo 1 > /sys/class/gpio/PI3/value
# echo 0 > /sys/class/gpio/PI3/value
