ALLNET 4duino Full-Color LED Module (ALL_OY_3211)

The ALLNET 4duino Full-Color LED Module (ALL_OY_3211) is a compact RGB LED breakout board designed for easy integration with Arduino, Raspberry Pi, and other microcontroller platforms. Featuring a 5 mm common cathode RGB LED with integrated current-limiting resistors, this module simplifies prototyping and educational projects requiring color mixing and PWM control.

Advantages

Integrated resistors reduce external component count, while the 4-pin interface (R, G, B, GND) enables straightforward connection to digital I/O pins. The module operates at 3.3V to 5V DC, making it compatible with both 3.3V and 5V logic systems. Two mounting holes allow secure attachment to breadboards or enclosures.

Suitable for

• Arduino and Raspberry Pi projects
• Color mixing and PWM demonstrations
• Indicator lights and status displays
• Educational electronics kits
• Prototyping and hobbyist applications
