Five black rectangular power modules with pin headers and USB ports

BUCIER

BUCIER 5pcs 3.3V 5V Breadboard Power Module 102

SKU CH-97HE-179X4

Five modules deliver switchable 3.3 V or 5 V at up to 700 mA from a 6.5–9 V DC or USB source for MB102 breadboards

  • ColorBlack
  • Weight2.08 ounces
  • Switchable 3.3V or 5V output matches circuit needs
  • Dual independent rails power separate sections simultaneously
  • Accepts 6.5-9V DC or USB input for bench flexibility
  • 700mA maximum current drives typical prototype loads
  • Five modules in one pack supports multiple builds

Breadboard power module kit

This pack contains five identical 3.3V and 5V power supply modules designed for MB102 prototype breadboards. Each unit accepts 6.5-9V DC or USB input and provides switchable output voltages. The modules suit hobbyists, students and engineers building low-power analogue or digital circuits on solderless breadboards. No prototype board is included in the package.

Steady 700mA output per rail

Under continuous load each module delivers up to 700mA across the two independent output pins. The onboard slide switches let you select 0V, 3.3V or 5V for each rail without rewiring. Regulation remains stable during extended prototype sessions powered from a DC jack or USB source. Thermal limits are reached only when both rails draw near the maximum simultaneously.

Replaces single fixed-voltage regulators

The kit replaces individual linear regulators or bench supplies when you need dual-rail 3.3V and 5V power on a breadboard. The jump is worthwhile for projects that mix 3.3V logic with 5V peripherals and require quick voltage changes. Builds needing higher current or adjustable voltage beyond 3.3V and 5V will need a different solution.

Questions about this item

Does the BUCIER 102 module generate much heat or noise when powering a breadboard circuit all day?

The module has no fan and no moving parts, so it runs silently; heat will depend on how close the load stays to the 700mA limit.

What external power source must I already have to run the BUCIER 102 board?

You need either a DC supply between 6.5V and 9V or a USB port that can deliver the required current.

Will the BUCIER 102 work with the older MB102 prototype boards I already own?

Yes, the module is designed to plug directly into MB102 breadboards and provides switchable 3.3V or 5V rails with independent control for each side.
