ブレッドボード電源キット 5V / 3.3V

Fits the breadboard and really easy to assembly even for beginners in electronics (as I am). Reliable so far.

This circuit is easy to build, but since it does not come with a build sheet; besides soldering experience you should have access to resistor color code information (for correct placement of resistors). The only other component that is tricky to place is the Power LED which must be installed in the correct orientation (not marked like electrolytic caps; lead length is the clue). You best test the LED to determine the + pin orientation before soldering in place. I also found the output voltages to be 3.21 (for 3.3 setting) and 4.88v (for 5V setting). The last comment is that the breadboard pins are in line on the circuit board, but when you plug into the solderless breadboard the power bus lines are offset slightly which means the power supply board does not sit square on the breadboard (not a big issue just an observation). It would have been nice if the circuit board offset the breadboard output pins to match the breadboard.

3.3 and 5 V. Fit's standard BB. Must be assembled from a kit. Short circuit protected. Works.

Works great, fairly simple to assemble as long as you can solder.
