arduino Power Supply Breadboard 3.3V 5V Power Supply Module+Minidodoca 9V 1A Adaptor 5.5 x 2.5mm+Alligator Clip Test Leads+Banana Plug Kit for Arduino UNO, Raspberry Pi, STM32 Electronic DIY etc

Almost a must buy for anyone using a breadboard and getting into electronics. Very modular power settings, and simple and effective functionality.

this kit allows me to be extremely flexible when testing led strips and micro controllers. Test your voltage input before you plug it into a micro controller. The power brick puts out 5v. the adapter will put out a reasonable 3volts but the 5volt side does not produce anything near 5volts (as has been commented on for that device). If you only need 3volts just be aware of how you've set the dongles. If you need 5volts, for a led strip say, use the brick but don't use the adapter.

All good.

The wall plug works well.The Dupont wires are fine, though the alligator clips are slippery inside of the covers.The banana plugs won't screw small enough to hold the dupont wire without bending it, unless I shim it with conductive material. They fit my meter snuggly, which is probably a good thing.The power board didn't quite fit any of my breadboards until I bent the pins a bit. It looks like some other pins are crooked, as well. It takes 7-12 volts, while an ELEGOO one I have is 6.5-9 volts, for comparison. Both only reach about 3v with the 5v setting when using a 9v battery and the connector from this kit. ELEGOO does a little better, but this one can apparently take higher input voltage, so a 12v battery might do better?

I love the fact Arduino kits are so cheap. Thank you

I like that this kit has multiple ways to power my Arduino boards. A great option.

Easy to add 3.3 or 5 volts to your breadboard electronics experiments. It only supplies about 800ma of current, which may be an issue when including servos or other motors.
