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

I typically have a lot of projects running at once. I use these boards to allow me to swap between projects without having to tear the old one apart or use another uno.

These are exactly as described! I needed it for a small custom circuit that plugs into an old alarm system, and it's done it's part of the job nicely!

uno dei pezzi è arrivato con i piedini storti. sono riuscito a raddrizzarli però l'innesto nella Uno R3 non è semplice e inoltre mancano le connessioni di alcuni pin. Manca un riferimento alla scheda tecnica del prodotto.

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

Many others have noted that the SCL/SDA pins are missing from this shield and the seller has been aware of this since 2018 and has still not fixed the product description. I bought these to use with a Wemos D1 R32 board which is plug-compatible with the R3.Updated review to add that these shields are not stackable and they have no available solder pads for wiring. HiLetgo shouldn't even be calling this a shield. Except for having a couple of LEDs and switches, this doesn't provide much benefit over just plugging Dupont wires directly into the Uno.Note to HiLetgo: This product could be nearly perfect with just a couple of changes. Use female headers with long pins and use a 10-pin header instead of 8-pin header to breakout dedicated SCL/SDA pins. This would free up the holes needed for soldering wires.

I feel this is a decent product for the price and worked for the purpose for which I am using it, but upon arrival several pins were bent. I straightened them out, no problem, but that could have gone south quickly if those pins broke off while straightening them.

Note to seller: I'm not going to edit my review in exchange for a refund.This is really more of a breadboard shield than a protoboard. Here are some shortcomings:- It was clearly designed for something that predates the Arduino Uno R3 (note: the board itself has a date from 2012 on it). It is missing the IOREF pin, and is missing the SCL/SDA pins above the digital header. Note that on the R3, these pins are tied to A4/A5, so you _can_ still use I2C devices with this, despite what some comments say. But you have to use A4 (SDA) and A5 (SCL) instead of the two dedicated pins.- None of the pads actually connect to the pins (except for 5V and GND)! There are female dupont headers on them, so you need to use jumper wire, which is not a permanent connection. I expected to be able to solder directly to pads which are connected to the pins. You can unsolder the female headers, but that's really annoying.EDIT: Having found a better protoboard, I realize the issue here. The outer row of pads, into which they have soldered regular pins, is _supposed_ to contain female headers with really long pins (as you'd find on other shields), and the inner row of pads is supposed to be for soldering the pins. Instead, they attached regular pins on the outer pads, and female headers on the inner ones. Somebody goofed in the manufacturing specs.- The connected pads are 3 rows deep, not 2, so you can't actually fit a DIP package on there and expect to be able to have connected pads on both sides.If you're designing a really small project with a single sensor, or perhaps an indicator, this might work. It does have two built-in LEDs and a switch. (The cathodes are connected through 1K resistors to GND, so they turn on in response to 5V or a high pin.). But for my application, they just got in the way.

Arrivate con piedini storti, alcuni connettori saldati storti e non in asse. Visto il costo non certo basso per il tipo di prodotto ci si aspetta un minimo di cura. Da evitare assolutamente. Peccato perché l'idea era interessante. Ne cercherò da altri fornitori, questo è assolutamente inaffidabile!

Very useful breadboard for the Arduino. It has holes to fit the prongs in a standardplastic case if one of the holes is enlarged a little bit and one of the prongs is cut down.The important I/O and supplies are supplied to the board through the connectors and thereis a plastic breadboard that can be stuck to the breadboard or the holes in the breadboarditself can be used for mounting devices on.

As noted in another review, the topside pin sockets are inset so this will have to be your topmost shield. I knew this going in so no problem there.There's no passthrough for the ICSP header but there is a place to connect your own since it's in a completely different place on the shield. Again, no problem for me because I don't need it, but this may be a problem for others.The pins aren't very long. I need to stack it on top of a DMX shield so I had to get an extra set of stacking headers (refer to the photo).... and it's those stacking headers that made me realize ... it's missing pins. The R3 has 3 extra pins (and one extra NC) that are not passed through. On the digital/PWM side, the AD4/SDA and AD5/SCL pins are missing, and on the Power block, it's missing the IOREF and an extra unused pin. Again, for me, none of this matters for my project, but it could be a problem for others.So with these deficiencies, why still 4 stars? Because it's cheap, it meets my needs perfectly, and got here quick.
