myVolts Breadboard Power Supply 3.3V 5V 53x11mm

SKU CH-MH8P-4JTW7

A 53 x 11 mm breadboard power module that supplies switchable 3.3 V or 5 V output with current-limiting protection up to 500 mA

  • TypeAT
  • Switchable 3.3 V or 5 V output fits project needs
  • Current-limiting protection guards circuits from overload
  • Compact 53 x 11 mm footprint matches standard breadboards
  • Popular pin header interface simplifies wiring
  • Up to 500 mA supply current powers small prototypes

Breadboard Power Module

The myVolts Breadboard Power Supply fits standard breadboards with its 53 x 11 mm footprint. It delivers switchable 5 V or 3.3 V output at up to 500 mA from a 5 V input. Current-limiting protection guards experimental circuits during prototyping and maintenance work.

Thermals Noise Power

The module draws power from a 5 V source and regulates it to the selected output voltage. Current-limiting protection activates when draw exceeds 500 mA, preventing damage to the supply and the circuit under test. No active cooling is required for normal bench use.

Upgrade Context

This supply replaces makeshift regulator wiring or fixed-voltage modules when a project needs both 5 V and 3.3 V rails on a single breadboard. The jump is worth it for hobbyists and engineers who frequently switch logic levels and want built-in current limiting without extra components.

Perguntas sobre este artigo

How do I install the 53x11mm module on a breadboard and set the correct voltage?

Align the pins with the breadboard power rails, press firmly until seated, then slide the onboard switch to select 3.3V or 5V output before powering the circuit.

What maintenance does the current-limiting protection require over time?

No routine maintenance is needed; the built-in protection resets automatically after an over-current event, so just verify the switch position before each new project.

At what load does the 500mA limit engage during continuous operation?

The module supplies up to 500mA; sustained draws at or above that level trigger the current-limiting circuit, which reduces output until the load drops back within range.
