KeeYees ESP32 Breakout Board

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.

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!

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.

Works with KEYESTUDIO Mini ESP32 Development Board with ESP-WROOM-32 Microcontroller. Very happy. The soldering on the screw terminals is a like uneven but otherwise they’re great.

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...

I gave this 5 stars because I think it's a quality product. But I had to return it because the ESP32's I have do not fit. This was my fault as I didn't read the description carefully enough. There are (at least) 2 versions: one for the 30 pin ESP32 and one for the 38 pin version. I bought the wrong one.

The first board was great, a real bargain, the best! The second board was obviously a test of will. One header was correctly pointed out, the second was pointed in. Me, being up to the challenge presented, desoldered the pointed in header and turned it around. My work friends gave me judgmental looks. When complete, this was my preferred board. Thank You, it was fun. 😊

This KeeYees ESP32 breakout board (GPIO 1-to-2 expander for 38-pin versions) didn’t work for my ESP32-S3 development kit 38pin version. The female pin headers are too narrow, so it doesn’t seat properly on the standard male pins. Such a shame as the description says it works, but clearly it doesn’t. Returned it.

dont buy this product if you have esp32 wroom chip 2mm short on width length ok i now have 4 boards i cant use brian (electronics project) cost 12 quid wasted

Die Anschlüsse passen nicht zum ESP 32 Board.

Petites cartes bien pratiques, mais attention à la version que vous choisissez. En effet il existe différents type d'ESP32 avec plus ou moins de pin.

Fits the Kidsrobot 38pin board I bought a while ago. Works well. https://a.co/d/hoXqE4X

Attention, si cela rend le prototypage beaucoup plus facile, ces cartes ne conviennent qu'aux ESP 38 pins (2 x 19 pins , rangées séparées de 2,54cm). On peut néamoins les utiliser pour des µC de plus petit nombre de pins, sous réserve de la largeur qui doit être semblable (2,54cm) et en faisant abstraction des intitulés des pins (qui devient inadéquat). Note : On peut aussi les associer à des "breadboards" si la connexion directe avec des câbles s'avère impossible ou délicate.
