Description
Product Overview
The Q-BAIHE 405nm 445nm 450nm Laser Diode LD Driver Board is engineered to deliver precise, constant-current power to a wide range of laser diodes used in additive manufacturing, optical research, and hobbyist projects. Built around a robust step‑down regulator, the board accepts a flexible DC input voltage of 8 V to 14 V, automatically stabilizing the output to a selectable 12 V level while maintaining a current range from 200 mW up to 2 W. This ensures that both low‑power and higher‑power diodes operate within their optimal parameters, extending component lifespan and improving beam consistency. The driver incorporates TTL modulation capability, allowing users to encode data or synchronize laser activity with external controllers, a feature essential for 3D printing, engraving, and scientific instrumentation. Its compact footprint—measuring just 2.99 × 2.17 × 0.51 inches—and lightweight construction (0.46 oz) make it easy to integrate into tight enclosures or portable setups. The board is fully compatible with AC and DC power sources, and its polarity‑agnostic design simplifies wiring for non‑professional users, reducing the risk of connection errors.

Usage
Designed with versatility in mind, this driver board fits seamlessly into a variety of environments. In a 3D printer, it can be paired with resin‑based SLA or DLP systems to precisely control the curing laser, delivering consistent exposure across each layer and improving print accuracy. For laser engraving, the board’s TTL modulation enables high‑resolution patterning on materials such as wood, acrylic, and metal, while the constant‑current output guarantees uniform line depth and color fidelity. Researchers employing spectroscopy or optical trapping benefit from the board’s stable output, which minimizes intensity fluctuations that could compromise experimental data. The wide input voltage range also allows the board to be powered from portable battery packs for field work, and its ability to handle both AC and DC inputs means it can be integrated into existing power infrastructures without additional converters. Whether mounted inside a custom‑built enclosure, a handheld device, or a laboratory bench setup, the driver’s reliable performance and straightforward wiring make it a go‑to solution for anyone needing precise laser control.

FAQ
What laser diode wavelengths are compatible with this driver?
The board is optimized for diodes operating in the 405 nm, 445 nm, and 450 nm ranges, but it can also drive other wavelengths as long as the required current stays within the 200 mW‑2 W output window.
Can I use this driver with a battery pack?
Yes. The driver accepts DC input from 8 V to 14 V, so a portable battery pack that supplies voltage within this range can power the board, making it suitable for field‑use or mobile setups.
How does TTL modulation work on this board?
TTL modulation allows the driver to receive a digital signal (0 V or 5 V) that turns the laser on or off rapidly. This is useful for encoding patterns, synchronizing with motion controllers, or creating pulse‑width‑modulated (PWM) intensity control.
Is the driver protected against over‑current or overheating?
Yes. Built‑in protection circuits monitor current and temperature, automatically reducing output or shutting down the board if unsafe conditions are detected, thereby safeguarding both the driver and the attached laser diode.
What warranty does Q-BAIHE provide?
Q-BAIHE offers a one‑year limited warranty covering manufacturing defects. During this period, defective units can be repaired or replaced at no cost, and technical support is available to assist with installation and troubleshooting.
