The W04 is the higher-capacity member of the Wi-Fi asynchronous range, at roughly 448×112 pixels, which we recommend for larger or content-richer scrolling signs and lettered boards. You upload the content wirelessly through a phone app, after which the card plays it on its own with no computer, in 24-hour daily operation if need be. We back reliability with a 1-year warranty, spare parts held in stock and module replacement that takes minutes. We recommend it to larger shops, restaurants and service centres, where several pieces of information, a logo and text all have to be shown at once.
LED wall controller W04
We recommend the W04 card to anyone for whom the W03's capacity would already prove tight, but who wants to keep the convenience of cable-free Wi-Fi content management. The greater pixel capacity and larger memory let the sign display several more detailed pieces of content at once, longer scrolling text or more complex graphic elements. Over the Wi-Fi connection, refreshing the content can be done conveniently, even remotely, while asynchronous operation ensures continuous, uninterrupted playback. The modules are shipped after quality control with bin-matched LED chips, so the larger surface stays uniform.

More content, the same convenience, the right viewing distance
If your sign is larger, or if you regularly want to display more information — a logo and text at once, for instance — the W04 provides the headroom you need over the W03. The card keeps all the convenience of the Wi-Fi controllers, so content is still refreshed from the phone app with no cable. The larger buffer makes content switching smoother and faster, which matters particularly if you refresh the sign several times a day. Medium and larger shops, restaurants and service centres often choose this level when the capacity of the smaller cards is no longer enough, typically in settings with a viewing distance of 4–8 metres.
Handling, stability, warranty
Once you have set the text, images, effects and scheduling in the phone app, the content goes to the card over the Wi-Fi connection; the card stores it in internal memory and plays it back on its own, continuously and independently of the network. This operating principle ensures that a network dropout does not interrupt the display's continuous operation. The W04 delivers stable, reliable performance even in continuous use up to 24 hours a day. We give a 1-year warranty on the card, which provides long-term security for operation.
Why you need not fear a compromise on quality
When you choose a larger sign, it is a fair expectation not to have to worry about long-term reliability. In the modules that go with the W04 we use the same quality-controlled, bin-matched LED chips as in our premium-class systems. In the event of a failure the modular build means the faulty element is accessible from the front and can be swapped in minutes, and we supply the part from regional stock with service backing behind it, rather than waiting weeks on an overseas supplier. Alongside the warranty you can also choose a Warranty+ package, if downtime would mean a direct loss of revenue for your business.
Running it: consumption and training
The consumption of the larger sign that goes with the W04 typically runs at around 40–60 W/m² in average operation, higher at peak load, but even so the monthly electricity for a 3–4 m² sign remains a well-plannable item. Operation through the phone app is just as simple as with the smaller cards: if you can write an email you will learn to handle this too, and as part of the handover we run practical training for your staff.
Typical applications
LED wall controller W04 — frequently asked questions
How does the W04 differ from the W03?
The W04 has greater pixel capacity and more memory, so it is recommended for larger signs and content-richer display.
Can I refresh the card without Wi-Fi?
A Wi-Fi connection is needed to upload content, but not for continuous playback, since the content is held in the card's memory.
How long does a content refresh take?
Uploading from the phone app typically completes within a few minutes, depending on the size of the content and the network speed.
What is the warranty, and what if something breaks?
We give a 1-year warranty; because of the modular build the faulty element can be swapped in minutes, and we supply the part from regional stock with service backing behind it.
Who trains my colleagues to use it?
As part of installation and handover we run practical training for your staff, so they can carry out the daily content refresh confidently on their own.
Is consent needed if the sign goes somewhere clearly visible from the street?
Signs visible from public space often require a townscape notification; we help with that process so you avoid a fine.
