SMARC vs Qseven: Which Low-Power Computer-on-Module to Choose?

→ COM / SOM→ SMARC→ Qseven

For battery-powered, fanless and compact devices, two system-on-module standards dominate: SMARC and Qseven. Both support ARM and x86 processors at low power, but they do not have the same future.

SMARC: the modern choice

SMARC modules measure 82 × 50 mm (short size) and use a 314-pin MXM3 connector. SMARC 2.1 adds MIPI-CSI camera inputs, up to 4 Ethernet ports with TSN and modern display interfaces. Processors range from NXP i.MX 8M Plus and i.MX 9 to Intel Atom x7000E, many with an NPU for edge AI.

Qseven: proven and cost-effective

Qseven modules measure 70 × 70 mm and use a 230-pin MXM2 connector. The standard is mature and well suited to existing designs, but new processor launches increasingly favour SMARC.

How to decide

  • New design with camera, AI or TSN needs: choose SMARC.
  • Existing Qseven carrier board: stay on Qseven and secure supply, then plan a migration to SMARC.
  • Very cost-sensitive, simple I/O: both can work, compare module prices for your volumes.

Long-term availability matters

Low-power modules often go into products sold for 10 years or more. Check the vendor roadmap and lock your bill of materials. Our OEM+ Program helps keep your module stable over time.
