Lighting LED controller Aqua-Computer farbwerk USB — 12 V, 2.5 A, black

The Aqua-Computer farbwerk USB is a compact four-channel LED lighting controller designed for RGB and ARGB strips. It accepts 12 V input and supports up to 2.5 A, offering precise color control with 13‑bit resolution per channel (8192 steps) for smooth gradients and low-brightness fidelity. The unit operates as a standalone device with an embedded microprocessor, can be controlled via USB when connected to a host, and includes multiple inputs for temperature sensors or other 0–3.3 V signal sources. The black housing and small footprint make it suitable for integration into PC cases and custom lighting projects where space and reliable color reproduction matter.

Advantages

The farbwerk USB delivers high color resolution across four channels, enabling fine-grained color mixing and near-continuous transitions. Its autonomous operation allows it to run without a PC while USB connectivity provides additional control and integration with system software. Multiple sensor inputs permit dynamic visualization of temperature or external signals as color changes. The controller’s compact design and 12 V power compatibility simplify installation in standard PC lighting setups and bespoke LED applications.

Suitable for

• PC case RGB or ARGB lighting setups
• Custom LED strip installations requiring precise color control
• Visual temperature indication using compatible sensors
• Small electronics projects using 0–3.3 V inputs or potentiometers

Key specifications

• Operating voltage: 12 V
• Maximum current: 2.5 A
• Channels: 4 outputs (can address up to 12 channels in combinations)
• Color resolution: 13‑bit per channel (8192 steps)
• Control interfaces: USB connectivity and standalone operation
• Sensor inputs: 4 inputs compatible with temperature sensors or 0–3.3 V signals
• Housing color: black

How to use

Connect the controller to a 12 V supply and attach compatible RGB or ARGB LED strips to the output channels. For PC integration, plug the unit into a USB port to enable software control and scene management; when disconnected from USB the device can run independently using stored settings or built-in modes. If temperature monitoring or external signal visualization is required, connect compatible sensors or 0–3.3 V signal sources to the dedicated inputs. Configure channels, color profiles and effects through the accompanying software or via the device’s standalone controls according to the installation manual.

Usage recommendations

Use LED strips and peripherals rated for 12 V and ensure the combined current draw does not exceed the 2.5 A limit. When connecting temperature sensors, follow the manufacturer’s instructions for sensor compatibility and placement. If you intend to use the sensor inputs for potentiometers or other 0–3.3 V signals, verify voltage ranges and wiring to avoid damaging the inputs. For installations outside of a PC, ensure appropriate insulation and mounting; for applications requiring higher voltages or currents, select a controller matched to those requirements.
