SoM340 System on Module: Building a High-Performance ARM Motion Control Core Platform

In the era of rapid evolution in smart manufacturing and automation equipment, the motion controller serves as the "brain" of the machine, undertaking critical tasks such as coordinating multi-axis movements, executing precise trajectory planning, and delivering real-time responses. The SoM340 System on Module (SoM) launched by Beilai Technology, based on Allwinner Technology's T507-H quad-core ARM Cortex-A53 processor, stands out with its superior computing power, low power consumption, and abundant industrial interfaces, making it the ideal choice for next-generation domestic motion control platforms.

High-Performance ARM Core Driving Precise Control

The SoM340 features a 64-bit quad-core Cortex-A53 architecture with a clock speed up to 1.416GHz, supporting operating systems such as Linux, Linux-RT, Ubuntu, and Android, while being compatible with the Qt 5.12 graphical interface development environment. In multi-task real-time control scenarios, it efficiently handles path planning, servo signal analysis, and human-machine interface rendering, providing robust computing support for complex mechanical equipment.

• CPU: T507-H, quad-core 64-bit ARM Cortex-A53
• GPU: G31 MP2, supporting OpenGL / Vulkan / OpenCL
• Memory Configuration: 1GB / 2GB DDR4 + 8GB / 16GB eMMC
• Power Consumption: Only 2.15W at full load

This configuration not only suits high-speed motion control cores but also seamlessly integrates image display and algorithm computation, achieving deep fusion of control and vision.

Abundant Interfaces Meeting Complex Control Demands

Motion control imposes stringent requirements on interface real-time performance and precision. The SoM340 exposes over 170 pin resources via a stamp-hole design, covering all core interfaces essential for industrial control:

• Multi-channel ADC (12-bit precision) — Precisely capturing analog signals like torque, current, and displacement;
• Dual Ethernet ports (supporting gigabit RMII/RGMII) — Building EtherCAT or Modbus TCP networks;
• CAN bus and RS485 expansion interfaces — Enabling communication with traditional PLCs and sensors;
• 4 USBs, HDMI, LVDS, MIPI-CSI — Supporting HMI screens and industrial camera connections.

Additionally, the SoM340 includes built-in IgH EtherCAT master and SPI-to-CAN driver examples, facilitating rapid deployment of EtherCAT servo control systems for multi-axis synchronization and real-time motion.

Real-Time Systems and Visualization Development Support

The SoM340 is compatible with various real-time operating systems and development tools, including:

• Linux-RT Real-Time Kernel — Precisely managing servo synchronization and interrupt responses;
• Docker + Node-RED — Rapidly building cloud-edge collaborative logic;
• Qt 5.12.5 — Developing high-performance industrial human-machine interfaces (HMIs);
• OpenCV / AI Modules — Supporting vision guidance and intelligent inspection.

These features empower the SoM340 to go beyond traditional motion control, seamlessly integrating AI, data acquisition, and remote monitoring to serve as a core computing node in smart factories.

Typical Application Scenarios

With its high reliability and flexible scalability, the SoM340 finds broad applications across automation equipment:
