, you can turn any HDMI-ready screen into a high-impact digital display. Whether it's a pop-up shop, a trade show booth, or a mobile event, our open-source software makes portable digital signage a breeze. Just grab your Raspberry Pi, flash the Anthias OS
While digital signs are traditionally permanent fixtures bolted to walls in retail stores or corporate offices, a growing trend focuses on . Deploying Anthias on a compact, battery-powered, or easily movable hardware stack creates a plug-and-play marketing and information tool for events, pop-up shops, trade shows, food trucks, and field operations. What is Screenly Anthias?
Building a mobile digital sign requires software that is lightweight, reliable, and capable of offline operation. Anthias provides several distinct advantages for portable setups: Key Components of a Portable Anthias Rig Screenly
Anthias allows users to display high-quality video, images, and live web pages on any screen equipped with an HDMI port. Its lightweight architecture makes it the perfect candidate for portable, on-the-go digital signage applications. The Benefits of a Portable Anthias Setup
Digital signage has traditionally relied on fixed infrastructure, limiting its application in dynamic, temporary, or mobile environments. This paper examines Screenly Anthias , an open-source digital signage platform, and evaluates its viability for portable deployments. We propose a lightweight architecture leveraging Raspberry Pi hardware, battery power, and Wi-Fi tethering to enable fully portable digital signage. The study includes a technical deployment guide, power consumption analysis, and practical use cases such as event signage, emergency information systems, and mobile retail displays. Results indicate that Screenly Anthias, with minor configuration adjustments, can operate reliably in portable mode for 6–10 hours on standard battery packs, offering a cost-effective and flexible alternative to proprietary solutions.
At its core, Screenly Anthias is a lean, Linux-based digital signage manager optimized for the Raspberry Pi. Its portability stems primarily from its hardware compatibility. Because a Raspberry Pi is roughly the size of a credit card and requires minimal power, it can be easily integrated into mobile setups. When paired with portable monitors or battery-powered displays, Anthias becomes a self-contained broadcasting unit. This allows users to move their signage from a trade show booth to a pop-up shop or a classroom without the need for complex wiring or permanent installations.
A portable signage system must satisfy:
