The perfect companion for Arduino, ESP32, and Raspberry Pi Pico projects. Say goodbye to messy battery clips and unstable power connections! The MB102 Breadboard Power Supply Module is the ultimate convenience tool for any Maker working with solderless breadboards. Designed to plug perfectly into the power rails of a standard 400 or 830-point breadboard, this module regulates external power (from a wall adapter or battery pack) into a clean, stable supply for your electronics.

What makes this module a "must-have" is its flexibility. It features independent voltage selection jumpers for each side of your breadboard. This means you can power a 5V LCD screen on the left rail and a 3.3V microcontroller (like an ESP32 or Raspberry Pi Pico) on the right rail simultaneously—all from a single power source. With a built-in latching ON/OFF switch and LED indicator, you can safely kill power to your circuit without unplugging everything, saving your components from accidental short-circuits while you tinker.

Key Features and Benefits:

• Dual-Rail Independence – Select 3.3V, 5V, or OFF for each side of the breadboard independently using simple jumper caps.
• Standard DC Input – Accepts a wide range of input voltages (6.5V–12V) via a standard 2.1mm barrel jack, making it compatible with common wall adapters.
• Compact & Secure Fit – Designed to snap firmly into MB102 breadboards, reducing the risk of power wires slipping out during testing.
