Powering Up¶
The Power Module is the heart of your MICRORACK system. It converts the input from your power adapter into the stable voltages required by your modules.
Connecting the Power Module¶
- Identify the Power Rails: Most breadboards have two sets of rails on the top and bottom. These will carry the +12V, +5V, GND, and -12V voltages.
- Insert the Power Module: Place the Power Module at the far left or far right of your breadboard. Ensure the pins are firmly seated in the power rails.
- Check Orientation: Ensure the Power Module's triangular notch is pointing towards the bottom of the breadboard.
Power Supply Requirements¶
| Parameter | Requirement |
|---|---|
| Voltage | DC (confirm voltage with your specific Power Module) |
| Polarity | Center-Positive (standard for most gear) |
| Current | Minimum 500mA recommended for small-medium setups |
Voltage Rails: The system provides +12V, +5V, GND, and -12V to the breadboard rails. Modules use internal regulators as needed.
The "Smoke Test"¶
- Plug your power adapter into the Power Module.
- Turn on the power switch (if applicable).
- Check the LEDs: The Power Module should have indicator LEDs. If they light up, your system is ready!
- If the LEDs do not light up, turn off the power immediately and check:
- Power adapter is plugged in and working
- Correct polarity
- Power Module orientation (notch at bottom)
Tip: One Power Module can power multiple breadboards if they are chained together. See the Power & Expansion section for more details.
What If Nothing Happens?¶
- No LEDs: Check power supply connection and polarity.
- Module doesn't work: Check orientation — notch should be at the bottom.
- Intermittent power: Ensure all pins are fully inserted into the breadboard.
