Zotac's CM5-PICO Is the Smallest, Most Feature-Dense Raspberry Pi CM5 Mini PC Yet — ISE 2026 Debut

A Compute Module 5 Mini PC That Finally Brings Everything to the Party

Zotac is set to unveil the CM5-PICO at Integrated Systems Europe (ISE) 2026 in Barcelona, and the spec sheet makes a strong case that this is the most feature-dense Raspberry Pi CM5 mini PC anyone has shipped to date. The chassis measures just 114.8 x 76 x 31 millimeters, the entire system is passively cooled, and it manages to fit dual 4K HDMI outputs, dual USB 3.2 ports, a USB Type-C port, Gigabit LAN, two M.2 module slots, dual CSI-2 camera interfaces, an RS232 header, a PWM fan header, and the full 40-pin Raspberry Pi HAT header inside that aluminum shell. For makers, digital signage integrators, industrial IoT builders, and anyone who has been waiting for a serious productized CM5 platform, this is the launch worth tracking.

The CM5-PICO is built around the Raspberry Pi Compute Module 5 — the Broadcom BCM2712 quad-core Cortex-A76 SoC running at 2.4 GHz, paired with up to 16 GB of LPDDR4x-4267 memory. That is the most capable Raspberry Pi compute platform available today, and Zotac has engineered a carrier board that takes full advantage of every interface the CM5 exposes. The result is a small board computer that can credibly serve as an edge AI gateway, a 4K-capable digital signage player, an industrial IoT hub, or a compact computer vision node — all from a single hardware design.

Why the Dual M.2 Slot Layout Is the Headline Feature

The single most interesting design decision in the CM5-PICO is the two M.2 slots. The board includes one Key-M 2280 slot and one Key-B 3024 slot, which together open up the kind of expansion flexibility that single board computers rarely offer at this size. The Key-M slot accepts standard NVMe SSDs for fast local storage — meaning the CM5-PICO can boot from NVMe and host meaningful workloads locally without leaning on a microSD card. The Key-B slot accepts 4G/5G cellular modems for connected edge deployments, dedicated NPU accelerators for AI inference, or other M.2-based expansion modules. That combination is what turns a CM5 carrier board into a real productized platform.

The NPU Slot Quietly Makes This an Edge AI Box

The 3024 form-factor Key-B slot is the same physical interface used by several of the popular M.2-based NPU modules now shipping in 2026. Pairing the CM5 — which is a capable general-purpose CPU — with a dedicated M.2 NPU adds tens of TOPS of inference performance to the chassis without changing any of the existing peripheral layout. For makers and integrators building real-time object detection, license plate recognition, or vision-based industrial inspection deployments, the CM5-PICO is the kind of platform where dropping in the right NPU module is what tips the project from "interesting prototype" to "production-ready edge AI node."

The Industrial Interface Selection Tells the Real Story

The CM5-PICO's external port and header layout reveals the audience Zotac is actually targeting with this design. The dual 4K HDMI outputs are the digital signage and kiosk story — two displays, both at full 4K, driven from a passively cooled compact unit that mounts easily behind any monitor. The dual CSI-2 camera interfaces are the computer vision and industrial inspection story — two synchronized camera inputs feeding into the same compact compute node. The RS232 header is the legacy industrial integration story — RS232 is still the de facto interface for older industrial sensors, PLCs, and serial peripherals, and including it on the carrier board removes one more friction point for integrators.

The Full 40-Pin HAT Header Keeps the Maker Story Alive

Zotac wisely kept the full 40-pin Raspberry Pi HAT header on the CM5-PICO. That means the entire ecosystem of Raspberry Pi HAT add-on boards — sensor HATs, motor control HATs, environmental monitoring HATs, audio HATs, and the long tail of community-built add-ons — works on the CM5-PICO out of the box. For makers who already have a stack of HATs from previous projects, that compatibility is the difference between a board they can pick up tomorrow and a board they have to special-case.

Passive Cooling and the 114.8 x 76 x 31 mm Form Factor

The decision to ship the CM5-PICO with passive cooling in an aluminum chassis is the design choice that makes it deployable in places where active cooling would be an immediate liability. Digital signage cabinets, industrial control panels, in-vehicle deployments, and outdoor enclosures all benefit from a fanless design that has no moving parts to fail and no dust intake to clog. The 114.8 x 76 x 31 mm overall dimensions are roughly the size of two stacked iPhones — small enough to mount almost anywhere, large enough to dissipate the CM5's thermal output cleanly through the aluminum shell.

The PWM Fan Header Is the Optional Active Cooling Path

For builders who want to push the CM5 harder than the passive aluminum chassis can sustain on its own, the PWM fan header on the carrier board provides a clean upgrade path. Add a small fan, tune the PWM curve, and the same chassis can run sustained heavier workloads. That optional-active-cooling design pattern is how a single carrier board can serve both the fanless deployment use cases and the higher-performance maker use cases without forcing the user to choose at purchase time.

Why the CM5-PICO Matters for the 2026 SBC Landscape

The Raspberry Pi Compute Module 5 has been the most capable maker-friendly compute platform on the market since its initial release, but the carrier board ecosystem around it has historically lagged the raw compute power. The CM5-PICO is one of the cleanest expressions of what a thoughtful, productized CM5 carrier board can look like in 2026 — feature-dense without being cluttered, industrial-ready without losing the maker ethos, and small enough to deploy almost anywhere. For integrators evaluating compute platforms for kiosks, digital signage, edge AI, industrial IoT, and computer vision projects, the CM5-PICO is the kind of platform that earns a serious look.

The next watch items are pricing and channel availability after the ISE 2026 unveiling, the specific industrial design wins that get announced through the back half of 2026, and the M.2 NPU module pairings that integrators publish as reference designs. For makers and integrators tracking the single board computer space in 2026, the CM5-PICO is one of the most exciting CM5 platforms on the calendar.
