Adafruit 1054 Laser Diode 5mW 650nm Red
A 650 nm red laser module delivering 5 mW output, driven by 2.8 to 5.2 V DC at up to 25 mA, with 100 mm leads for direct wiring
- 5 mW 650 nm red laser for visible alignment
- 8 V to 5.2 V input works with common logic levels
- 100 mm wires simplify breadboard connections
- 11 mm diameter fits tight enclosures
- 25 mA max draw keeps power budgets low
Red Laser Diode Module for Embedded Projects
This 650nm laser diode module delivers a 5mW red beam and includes an integrated driver for direct connection to a 2.8V to 5.2V DC supply. It is suited for hobbyists and engineers building laser harps, trip-wire sensors or alignment guides. The unit is not a handheld pointer and requires an external power source.
Low Current Draw and Wide Operating Range
The module draws a maximum of 25mA, minimising thermal load and power-supply demand in typical use. It operates reliably from -10°C to 40°C without active cooling, so fan noise is absent. The encapsulated housing protects the diode during normal bench or enclosure mounting.
Stable Output Under Continuous Operation
With the integrated driver regulating current, the diode maintains consistent 5mW output during sustained operation rather than fading after a short burst. The 100mm flying leads simplify permanent wiring in fixed installations. The 10.11mm diameter and 32.82mm length allow placement in tight mechanical assemblies.

Questions about this item
How do I connect the 100mm red and black wires to a 2.8 to 5.2V DC supply?
Strip the wire ends, connect red to positive and black to negative of a 3 to 5VDC source, ensuring the voltage stays within the 2.8 to 5.2V range to avoid damaging the integrated driver.
Will the integrated driver or the 650nm diode need replacement after continuous use?
The module is a sealed unit with no user-serviceable parts; the diode and driver are designed to last the rated lifetime, so the entire unit is replaced if output degrades or it fails.
At what point does the 40°C operating limit affect the 5mW output during sustained use?
Continuous operation at or above the 40°C maximum ambient temperature can cause the output power to drop or the diode to fail prematurely due to thermal stress.
