Product Overview
The MB-102 Power Module is a must-have for any electronics hobbyist. It takes an input of 7V to 12V from a DC adapter and regulates it down to clean 3.3V or 5V power for your circuit. The unique design features two independent output channels, allowing you to have 5V on one side of your breadboard and 3.3V on the other simultaneously.
Connections & Controls
-
DC Input: 2.1mm Center-Positive Barrel Jack (7V – 12V).
-
USB Input: Type-A USB port (can be used to power the board or as a 5V output).
-
Power Switch: Latching button to turn the entire board on/off.
-
Voltage Select Jumpers: Two sets of jumpers to choose [5V | OFF | 3.3V] for each side of the breadboard independently.
-
Output Pins: Header pins on the bottom align perfectly with the standard power rails of a breadboard.
