The C16C-WIFI is a Wi-Fi asynchronous control card for smaller and mid-sized full-colour LED signs up to roughly 256×64 pixels, refreshed from a phone app with no cable. Once the content is uploaded, the card plays it on its own independently of the network, so a Wi-Fi dropout does not stop the sign. Training comes with it, so if you can write an email you will learn this interface in minutes. The card carries a 1-year warranty, spare parts are held in regional stock, and because everything is replaceable you are never left alone with a failure. We recommend it to small businesses, restaurants and shop-window signs, where the content changes daily or weekly rather than by the second.
LED wall controller C16C-WIFI
The C16C-WIFI card is recommended for anyone who wants to run a full-colour sign without plugging in a cable or carrying a computer to site for every content refresh. Over the Wi-Fi connection you can reach and refresh the display remotely from the phone app, provided the network settings allow it. The card works on the asynchronous principle: the uploaded content is held in its memory and played back from there continuously, regardless of whether any device is currently connected. This is a practical solution for smaller and mid-sized full-colour advertising signs and message boards. In manufacture we use quality LED chips and bin-matched components, so your display still shows a uniform colour years later, not just in the first month.

Who it is for, and the viewing distance at which it works well
The C16C-WIFI suits smaller shop-window signs, interior walls of retail units and restaurant menu boards best, where viewers typically pass the sign on foot at a distance of 2–5 metres. The pixel pitch of the modules it drives is optimised for that viewing distance: viewed closer up the pixel grid is visible, but at normal use distance that is not a concern, since the purpose of the sign is to catch the eye, not to deliver print-quality detail. If you want the sign to be visible to drivers on a busy road from 10–15 metres, it is worth choosing our larger, coarser pixel pitch modules and the higher-capacity D05+WiFi or E62 card. We recommend it to small businesses, salons, cafés and reception desks, where the point is fast, inexpensive commissioning and simple day-to-day content changes, not technical maximalism.
Wireless convenience and how commissioning works
The biggest advantage of the C16C-WIFI is that refreshing the content requires no physical access to the card: as soon as the phone and the controller are on the Wi-Fi network, you can simply upload new text, an image or a simple animation from the app. During initial setup you enter the Wi-Fi network details in the phone app, pairing takes a few minutes, and the choice of typeface, colour, speed and effect also happens in the app. This is especially useful at locations where the sign is hard to reach, high on a facade for instance. The card's pixel capacity reaches roughly 256×64 pixels in full-colour mode, which is ample for logos, lettering and simpler graphic elements, but we do not recommend it for continuous video.
Quality you can rely on, not throwaway kit
We understand if your first question is whether you are getting a card assembled from anonymous components that will fail quickly. That is why every C16C-WIFI card passes quality control before dispatch, and the accompanying modules use bin-matched LED chips so the sign does not become patchy over time. If an element does fail, there is no need to replace the whole sign: because of the modular build, the faulty unit can be swapped in minutes, and the part is supplied from regional stock with service backing behind it, not from weeks of importing. That is the difference between an anonymous webshop product and a genuine purchase with real support: we do not disappear after the sale, and alongside the warranty you can also choose a Warranty+ package for longer-term peace of mind.
Running it: consumption and ease of use in numbers
The C16C-WIFI itself draws little power; the average operating consumption of the smaller full-colour sign that goes with it typically runs at around 30–60 W/m², and at peak load (full white image, maximum brightness) that can be as much as double, but in real, mixed-content operation the lower figure is the norm. The monthly electricity for a 1 m² sign therefore comes to an item of a few euros, not a hidden cost. Control itself is extremely simple: if you can write an email on your phone, you will learn to use this app too, and at handover we give practical training as well, so you are not left alone with an instruction manual.
Typical applications
LED wall controller C16C-WIFI — frequently asked questions
Do the phone and the card have to be on the same network?
For reliable operation it is best to connect the phone and the controller to the same Wi-Fi network; the card also supports direct pairing in hotspot mode.
What happens if the Wi-Fi connection drops?
The content is held in the card's internal memory, so a temporary Wi-Fi dropout does not affect the display's continuous, standalone operation.
Is this card suitable for video-type content?
The C16C-WIFI is made primarily for text, logos and simpler animated full-colour content; it is not a system designed for continuous video playback.
How long does the LED module that goes with the card last?
Quality LED chips are typically designed for a service life of 80,000–100,000 operating hours, which at 12 hours a day means 18–20 years, and over 10 years even in continuous 24-hour operation.
Who fits it, and how long does it take?
Installation is carried out by our contracting partner or our own team, typically within a day for smaller signs, starting with a free site survey so we know exactly what is needed.
If I move to a larger sign later, does this card stay?
If you extend the sign in future it is worth moving to the higher-capacity D05+WiFi or E62 card, but the logic of the phone app stays the same, so you will not have to relearn the controls.
