PN: CM5-X2.21 · in production

Compute Module · CM5 · 56 × 41 mm

CM5. The eight-core SoM you can build a product on.

A 56 × 41 mm compute module with the RK3588S2 inside: eight 64-bit cores, a 6 TOPS NPU, Mali-G610 GPU, and three 100-pin board-to-board connectors carrying nearly every signal the silicon exposes. Industrial supply window, schematics in PDF, BSP in our public Yocto layer.

01SKUs · CM5 · CM5 Lite

Same form factor. Two silicon options.

CM5 and CM5 Lite share the carrier and the BSP. Pick CM5 when you need GPU + 8 cores; pick CM5 Lite when 6 cores and no graphics is plenty.

Eight cores in 56 × 41 mm.

RK3588S2 4× Cortex-A76 + 4× Cortex-A55, Mali-G610 MP4 GPU, 6 TOPS NPU, up to 32 GB LPDDR4x and up to 128 GB onboard eMMC. Industrial-grade B2B connectors for repeated mate / unmate.

05B2B connectors

3 × 100-pin industrial-grade connectors.

Convenient disassembly and re-mating for service. Same connector family across CM3, CM3I, CM3J, CM4 and CM5, so your carrier ages well.
