## Description

desertcart.com: KeeYees 2pcs ESP32 Breakout Board Shield GPIO 1 into 2 for 30PIN ESP32 Development Board : Electronics

Review: 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.
Review: 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!

## Features

- IMPORTANT: Only compatible with 30 pins ESP32 development board, ref asin: B0B9G74NNM. Not applicable to other versions.
- GPIO 1 INTO 2: This breakout board can expand one GPIO pin of esp32 development board to two, which is convenient for users to reuse all pins in smart home projects. Nice breadboard alternative.
- 2 TYPE CONNECTIONS: Pin Header & Screw Terminal. Just select them according to your purpose.
- DOUBLE-LAYER PCB: The expansion board is a double-layer board. One pin is wired on both sides. Therefore, the circuit is stable and highly reliable, and there will be no poor circuit contact and unstable signal transmission.
- UPDATED VERSION: Compared with the previous version, the board of this version has been soldered completely. No need to solder parts by yourself, which is very convenient to use.

### ⭐⭐⭐⭐ 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.
