Gravity: Digital piranha LED module - Blue

The Gravity: Digital piranha LED module emits a bright blue light suitable for interactive robotics and electronics projects. Operating across standard 3.3V to 5V logic levels, it is an ideal visual indicator for students, hobbyists, and educators working with microcontroller platforms.

Interactive lighting projects

This blue piranha LED module pairs easily with microcontrollers and sensor shields, enabling responsive installations such as ambient-light-activated displays and indicators.

Digital and PWM brightness control

The module operates using simple digital signals, turning on with a LOW signal and off with a HIGH signal. It also supports PWM output on the control pin for smooth brightness adjustments.

Optical and electrical specifications

The onboard LED delivers a blue output with a dominant wavelength of 460nm to 475nm and a 65-degree viewing angle. It accepts a wide operating voltage range from 3.3V to 5V.

Compact physical footprint

Measuring 30mm by 22mm and weighing only 5g, the board features standard power, ground, and digital signal connections for tidy wiring.

Included connection cable

Each unit is supplied with one blue piranha LED light module and one compatible digital sensor cable (SKU: FIT0011) for quick setup.
