MB102 Breadboard Power Supply Module (3.3V/5V)

Testing a circuit before deciding on a microcontroller still means it needs power from somewhere — the MB102 clips straight onto a breadboard's rails and supplies both 3.3 V and 5 V at once, so a dev board isn't doing double duty as the power supply.

What's on it

• Two independent rails, each jumper-selectable to 3.3 V, 5 V or off
• Barrel jack input (6.5–12 V) or USB for power in
• Twin AMS1117 regulators, rated to roughly 700 mA per rail
• Power LED and a physical on/off switch

Good to know

Fits standard full-size and half-size breadboards. Because the two rails run independently, it's an easy way to feed a 3.3 V sensor and a 5 V motor driver from the same breadboard without building a separate regulator circuit.
