What the Arrakis Pico Is
The Arrakis Pico is a family of fanless, DIN-rail mounted industrial computers from Welotec, designed for control cabinets and edge installations where space is tight and reliability matters. The series includes the Arrakis pico Mk3 and the newer Arrakis Pico Mk4, both built around low-power Intel Atom processors. They are typically used as headless or display-capable industrial nodes running Windows or Linux, and are commonly deployed in energy, manufacturing, and trackside applications.
Key Specifications and Design Traits
The Arrakis pico Mk3 is a fanless DIN-rail computer with an Intel Atom CPU (4 cores), up to 8 GB of RAM, and optional LTE Cat. 1/4 support, with an operating temperature range of roughly -20 °C to +70 °C. The Arrakis Pico Mk4 moves to an Intel Atom x6200FE dual-core processor on the Elkhart Lake platform, with a headless variant and a compact fanless chassis. Across the series, the defining traits are wide-temperature operation, DIN-rail mounting, fanless cooling, and long-term availability — the features that make a device suitable for an electrical cabinet rather than a desk.

| Wireless option | LTE Cat. 1 / Cat. 4 | Depends on configuration |
| Operating temp. | Approx. -20 °C to +70 °C | Industrial range |
What to Look For in a DIN-Rail or Cabinet-Mounted Computer
If you are evaluating an Arrakis Pico or any comparable industrial computer, the practical checklist is: fanless cooling (no dust ingress, no moving parts), a wide DC input range with surge protection, DIN-rail or VESA mounting, at least one gigabit Ethernet port (two is better for gateway and firewall roles), and an OS option that matches your stack — Windows 11 IoT/Pro, a mainstream Linux LTS, or a stripped embedded Linux. Serial ports, isolated digital I/O, and wide-temperature ratings matter if the unit sits next to drives, contactors, or transformers.
Typical Applications
Fanless DIN-rail computers like the Arrakis Pico class are used as protocol gateways and edge nodes in substations and smart-grid equipment, as machine-side HMIs and data collectors on production lines, as train-side or trackside controllers, and as always-on kiosk or signage controllers in unattended locations. The common thread is a cabinet environment with limited airflow, vibration, and a need for years of unattended operation.
Thinvent's Fanless Industrial and Mini Computers
Thinvent builds fanless industrial computers, mini PCs, thin clients, and all-in-one PCs for exactly these roles. Our mini PC and industrial PC lines use Intel processors — from efficient Celeron and N-series chips through 12th, 13th, and 14th generation Core i3 and i5 options — with configurations from 4 GB to 64 GB of memory and 128 GB to 1 TB of SSD storage, dual gigabit Ethernet on many models, and a choice of Windows 11 Pro, Ubuntu Linux 24.04 LTS, FreeDOS, or no OS. If you are looking for an alternative to the Arrakis Pico for a cabinet-mounted, fanless deployment, Thinvent's industrial and mini PC range covers the same low-power, always-on, dust-tolerant use cases with worldwide availability.
