Awesome for prototypes
Sometimes a breadboard isn't the right fit. The flexibility with the connectors is great when there are motor controllers or relays involved. Be sure to check the MCU board size though. Overall solid and handy.

Does what it needs to do
What can I say, ESP32 plugs in easily, screw terminals work as expected, great value.

Decent shield
Ordered this product twice—first time had no defects, but the second set had stripped out screws in the screw-down blocks. Plug-in ports still worked fine.

Great for testing
Bought these to breadboard some Arduino projects. Both worked without a hitch.

Perfect fit
I have two versions of the ESP32, one a 30 pin and one a 38 pin. This is the 30 pin version and my Arduino fit perfectly. I also purchased the 38 pin version but that did not fit well. I could bend the pins enough on the 38 pin version and make it work. 30 pin…. great!

Good quality, but WAY too expensive...
I've attempted to write this review multiple times now but for some reason it never goes through. Let's try this again. This brand, or seller, generally has great products for makers at decent prices. This item however is not the case. These are just too expensive for what they are. I will say, the quality is good. The solder joints look good, the screw terminals are straight, the socket headers are in line, and over its good... but that just doesn't justify the price. This is a pack of two, where most other sellers are giving three. You can even get three boards with features like a power socket, regulator, and all the supporting electronics for less than these. I will however point out that I specifically didn't WANT those extra features, which is why I got this type, but still. These are nice, but not worth over $6+ per board. They are SO overpriced that I deducted 2 stars solely for that...

Just the thing for these wide ESP-32 development boards
There are at least two variations of the ESP-32 board: a narrow 38-pin version ("NodeMCU") and a wider 30-pin version. The wide version is a PITA as it does not fit on a standard breadboard (too wide so no way to access pins on one side). The standard solution has been to place two breadboards side-by-side and have the ESP board "bridge" the two breadboards -- not an ideal situation. This breakout board solves that issue, albeit at the cost of not having space for additional components. I found the board to be well-made, if overpriced, but now my 30-pin boards are at last usable for projects.
