XD-42 Bread Board Power Supply Module 5V 3.3V

The XD-42 Bread Board Power Supply Module plugs straight onto the power rails of a standard solderless breadboard and supplies 5 V or 3.3 V to your circuit. Power it from a 7–12 V DC adapter through the barrel jack or from a USB cable, and set each of its two rails to 3.3 V or 5 V, so 3.3 V sensors and 5 V parts can share one breadboard.

XD-42 Bread Board Power Supply Module Specifications

• Input (DC jack): 7–12 V DC, 5.5 × 2.1 mm barrel jack
• Input (USB): 5 V
• Outputs: 3.3 V and 5 V, selectable for each of the two rails
• Output current: up to about 700 mA, depending on input voltage and heat
• Controls: on/off switch and power LED
• Fits: standard breadboards, with pins that plug into the + and − rails

XD-42 Bread Board Power Supply Module Applications

• Powering breadboard prototypes without a lab power supply
• Mixing 3.3 V and 5 V sensors, modules and ICs on one board
• Running circuits away from the computer with a wall adapter
• Testing displays, sensors and ESP8266 modules
• School labs, STEM classes and electronics workshops

What's in the Box

• 1 × XD-42 breadboard power supply module

Tip: Check the + and − marks on the module before plugging it in, so the positive pins land on the red rail and the negative pins on the blue rail. The regulators turn extra input voltage into heat, so use the lowest adapter voltage that works, such as 7–9 V, when drawing higher currents.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
