Open-Source Manual Power Switching System

Key Features:

• Independent Control: Toggle each module on/off individually with dedicated manual switches.
• Staggered Start-Up: Sequentially activates modules to accommodate high start-up currents and prevent power-up failures.
• Series Connection: Streamline wiring by connecting modules in series with dual power cables.
• Single Power Supply: Power all modules from a single source for a simplified setup.
• DIY-Friendly: Easy to assemble with basic soldering skills and readily available components.
• Expandable Design: Daisy-chain multiple systems together – there's no limit to how many modules you can control!

Perfect for:

• LIBRE-hub laser module users: Expand and enhance your laser projects.
• DIY Experimenters: Use laser technology safely and affordably.
• Makers & Tinkerers: Build custom laser tools and gadgets for fun and learning.

All the information you need is right here!

• Assembly & Wiring Instructions: The only component is a 3-pin manual switch with the following connections:
  • Pin 1 is soldered to the V+ line, that comes from the previous switch and goes to the next, providing a continuous path for power through the daisy chain.
  • Pin 2 is soldered to the laser V+ and acts as the switch control, connecting to pin 1 when closed, thus powering the laser module.
  • Pin 3 is soldered to the laser module's GND, completing the circuit for the laser when the switch is closed, and Pin 3 is also soldered to the GND line, that comes from the previous switch and goes to the next.
  • The switch toggles whether the laser module is connected between V+ and GND (on) or between GND and GND (off).
• Daisy Chaining:
  • This design allows for easy expansion. By connecting the OUT pin of one component to the V+ pin of the next, you create a daisy chain. This means you can control multiple laser modules independently with a single power supply. Each module has its own switch, so you can turn them on and off individually as needed.
