Customer Reviews

  1. Review by Ian verified purchaser

    Pins are wrong spacing for the breadboard I bought with this order. I had to do quite a bit of scientific bending to get it to fit. I also had to trim off one set of pins (I assume they are duplicates). (Posted on 14/08/2018)

  2. Review by Robin verified purchaser

    As another review noted (but I foolishly ignored), older breadboard which have numbers between the power strips and main grid probably wont fit this (or others) power adaptor. The headers and jumpers are still awesome, and I'll pick up a new breadboard or two soon (e.g. ADA64). (Posted on 22/12/2017)

  3. Review by James verified purchaser

    Teamed this up with the Half-size breadboard SKU: ADA64. Neat little package for circuit design and testing. Already have a larger breadboard, this will fill a niche when I need power as well. One thing I did notice is the tendency for it to move when plugging in a power supply. But easy to deal with that. The switch and led, 5V one side 3.3V the other, and extra power pionts make for a nice product. As always excellent delivery time and quality from Core Electronics.

  4. Review by Bob verified purchaser

    Nicely made little PCB. 9-12 VDC in apparently, as it arrived without any specs. Of course it isn't intended for the ignorant consumer, just us techo types. On/off switch which is really handy when testing, especially if you see smoke! USB socket for USB based projects, and selectable regulated 5V or 3.3V to Breadboard. There's my problem, My breadboards are very old, dare I say last century. This is made for a more modern, small width breadboard. However I do need a new one! (Posted on 29/08/2017)

  5. Review by Christos verified purchaser

    Great value for money (Posted on 18/08/2017)

  6. Review by Lindsay verified purchaser

    Speedy service, order well packed. Have placed a larger order due to the excellent service and reasonable prices. (Posted on 24/05/2017)

  7. Review by Ian verified purchaser

    Handy board that saves a lot of time bring 5v and 3.3v supplies to any breadboard. Definitely worth the money. (Posted on 7/09/2016)

  8. Review by Ray verified purchaser

    Great little addition to my breadboard. Very useful, can provide 5V one side and 3.3 the other if you wish. I would like a 12V option direct from the input socket as well, but it's not a deal-breaker. (Posted on 10/06/2016)

  9. Review by David verified purchaser

    haven't use this yet (Posted on 19/02/2016)

  10. Review by Clewsy - Bang-for-buck verified purchaser

    Very handy for breadboard prototyping. In case you didn't realise from the description, note it can be set to two separate source voltages - 3V3 and 5V simultaneously and independently. (Posted on 29/03/2015)

  11. Review by Sonytecho - Handy for prototyping verified purchaser

    Elegantly solves the problem of hooking up power rails to breadboard when prototyping a new circuit. Makes it quick and easy and less chance of blowing up an expensive new IC!
    Well made and delivered quickly. (Posted on 20/12/2013)

  12. Review by Daryl - Handy device verified purchaser

    This board should come with every breadboard. Cuts down wiring clutter, provides both 3.3V and 5V and accepts a range of power inputs.

    Only thing to note is to be careful with the jumpers to ensure you have the right voltage selected for your circuit. (Posted on 7/12/2013)
