Touchfly: Get to Know ARM Industrial Motherboards

An ARM industrial motherboard is a single board computer (SBC) built around an ARM-based processor and engineered for harsh, always-on environments. Unlike consumer boards, it is designed to run 24/7 inside factories, outdoor cabinets, and embedded devices without failure.

Main ARM Chip Platforms

Choosing the right ARM SBC starts with the SoC (system-on-chip). Here are the platforms most common in industrial designs:

Rockchip Processor

Allwinner Processor

MediaTek Processor

RockchipRK3288/RK3399/RK3568/RK3576/RK3588
AllwinnerA133, H618, A40i, H313
MediaTekMT8516、MT8788

Common Interfaces & Protocols for ARM Industrial Motherboards

Physical Interfaces

  • Serial: RS232, RS485, TTL-UART (Most widely used for industrial data acquisition)
  • Bus: CAN / CAN-FD, I2C, SPI, PWM, GPIO (DI/DO Digital Input & Output), ADC analog acquisition
  • Network: Gigabit / 100M Ethernet RJ45 (PoE optional), Wi-Fi, Bluetooth, 4G/5G module socket (Mini PCIe / M.2), SIM slot.
  • Display: HDMI, eDP, LVDS, MIPI-DSI (display interface); MIPI-CSI camera interface
  • USB: USB2.0 / USB3.0, Type‑C OTG
  • Storage: eMMC, TF Card (MicroSD), SATA (available on some high-end models)
  • Audio: I2S, 3.5mm audio jack, Speaker, MIC(microphone)
  • Power: Wide-range DC input (9~24V)

Communication Protocols

  • Serial Protocols: Modbus RTU (the mainstream for RS485)
  • Ethernet Protocols: TCP/IP, Modbus TCP; high-end models support EtherCAT, Profinet, EtherNet/IP
  • Low-level Bus Protocols: CAN 2.0A/B, CAN-FD, I2C, SPI
  • Upper-layer IoT Protocols: MQTT, HTTP, OPC UA, SNMP

How Buyers Should Choose

When you search to buy an ARM industrial motherboard, you are really evaluating a partner, not just a part. Consider:

  1. Manufacturer vs. trader. A direct ARM SBC manufacturer / factory controls quality and lead time. TouchThink is a professional ARM industrial motherboard manufacturer and supplier with in-house R&D.
  2. OEM / ODM flexibility. Can they customize the ARM board to your mechanical and I/O needs? Look for custom ARM board China capabilities.
  3. Certifications. CE and FCC are the baseline for export.
  4. Lifecycle & support. Industrial projects run for years — confirm long-term supply of the ARM SBC.
  5. Wholesale & MOQ. If you need ARM industrial motherboard wholesale, discuss volume pricing and minimum order quantities upfront.
