DESCRIPTION

Simple but useful device that provides LED light from a standard USB port.

PACKAGE INCLUDES:

  • Qty 2 – Mini USB LED Light Module

KEY FEATURES OF MINI USB LED LIGHT MODULE:

  • 3 SMD white LEDs
  • Pure white light
  • Built-in current limiting to 60mA
  • 5V operation

The module can be plugged into a standard USB Type-A port like with a USB extension cable where it pulls 5V power from the port and lights the LEDs.  It can be plugged into a USB port on a battery to provide a small portable light or in something like an unused USB port of a phone charger to provide a night light or for similar applications.

The device includes a 39 ohm current limiting resistor which limits the total current draw to 60mA @ 5V with the LEDs in parallel, so each LED pulls approximately 20mA.  This keeps the LEDs within safe operating characteristics.

A 5V source can also be soldered to the two power leads to add a small light source to a project.  The 60mA drive requirement is too high to drive directly with an output pin on an MCU, but a transistor can be added to increase the drive capability so that the light could be controlled on/off.  The LEDs will light over over the range of 3.3V to 5V, but will be at reduced brightness at lower voltages.

BEFORE THEY ARE SHIPPED, THESE MODULES ARE:

  • Packaged in a resealable ESD bag for protection and easy storage.
