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