Sorry, no stores were provided.

  • You can try Amazon or eBay for "mainstream" single board computers, or Aliexpress, Banggood and GearBest for China-based SBCs.
  • For industrial single board computers, you can try requesting a quote either on the official website or (sometimes) on Alibaba
  • You can also suggest a (possibly international) store using the "Report mistake" feature.

Product Description

The 68.7 x 31mm Compute Module 3 (CM3) integrates the guts of a Raspberry Pi 3 (1.2GHz-clocked quad-core BCM2837 SoC + 1GB RAM), plus 4GB eMMC storage. The module plugs into a standard DDR2 SODIMM connector and all additional processor interfaces are available via the edge-connector (many more GPIOs and I/Os than on a standard RPi SBC). The CM3L ("Lite") omits the eMMC flash.
