Review: son diferentes a los que vienen con elegoo, básicamente llevan una resistencia de las antiguas y led de los normales, es un detalle pero de funcionamiento son iguales y para proyectos caseros valen. en la foto la original a la derecha y esta a la izquierda
Review: Great value and fair quality - I have just ordered my second. Makes projects and prototyping easy.

### ⭐⭐⭐⭐⭐ Review
*by B***T on 8 February 2024*

I do a lot of development on Arduinos and STMicroelectronics boards. Both have connectors that align with Arduino Uno V3 pin layouts. As a result, I have a LOT of breadboards laid out in different ways. Honestly, sometimes dealing with a full or half length bread board creates some added complexity, especially if the circuits I'm prototyping don't have many components. Sometimes it's easier to pop one of these on top of whatever dev board I'm using and wire up a quick prototype. I use my workbench for other things and it's easy to drop my dev board into a drawer with its circuits and get back to it another time. When I use a larger breadboard, I have to be careful of the wires connecting it to the dev board. Plus, if I want to see how a particular circuit, like a custom waveform generator, performs with multiple dev boards, it's much easier to pop one of these off and plug it into another dev board. No more disconnecting and reconnecting a few dozen wires just to test a custom wave form! It also reduces the chance of wiring errors going from one dev board to another. I bought 2 packs (4 boards total) and that seems to be plenty for my current projects. Overall rating: 5/5 stars
