## Overview

This 2-piece ESP32 breakout board set features 38-pin compatibility with ESP-WROOM-32 microcontrollers, expanding one GPIO pin into two for enhanced project flexibility. Built on a durable double-layer FR-4 PCB, it offers stable, reliable connections with both pin header and screw terminal options. Fully pre-soldered for immediate use, it’s the perfect expansion for professional-grade smart home and IoT development.

## Description

Función:ESP32 expansion board can Expand 1 GPIO pin to 2, which greatly facilitates users to reuse pins for large-scale smart home projects.Nice breadboard alternativeFunction:ESP32 breakout board is safe and reliable and can be extended to various applicationsThe ESP32 breakout board has 38 pins and narrower width, compatible with circuit boardsSupport Lua program, easy to developThree modes are supported: AP, STA and AP + STAThe board features a 2.4 GHz dual-mode Wi-Fi and Bluetooth chip, the ESP-WR0OM-32, and 40-nanometer low-power technologySpecifications:PCB material: high quality FR-4 materialPCB layers: 2 layersPCB thickness: 1.6mmPads: tin platedSize: 7.8 * 6.3 * 1cmES P32 PINOUT:Tips: You can print this pin map in equal proportions andattach it to the top of the module to recognize the definition ofeach pinProduct list:2 x ESP32 Breakout Board

Review: Dimensions slightly inaccurate but its a cheaply made board anyway - These dimensions might be 0.3mm on the large size as im printing a housing to go around the terminals to make sure they never rotate (as I typically break them by tighting the terminals a bit too much) and to help mounting and vibration Oh and im soldering a gyro and acc to it
Review: Perfect for prototyping ESP32 systems - Not sure why some reviews talk about pin spacing issues as my ESP32-WROOM-32D devices fit perfectly. Really good for wiring up the ESP32 in production mode with external power supplies for example and being able to unplug the ESP32 for re-programming without interfering with external power supplies, or to enable easy replacement in the field should the device fail in the future. Picture shows a prototype device with ESP32 driving 8 mains solid state relays with six DS18B20 bus oriented (single data wire) temperature sensor inputs and it all works brilliantly.

## Features

- 【COMPATIBLE】: ESP32 breakout board compatible with 38-pin narrow hole and no mounting hole version esp32 development board, not suitable for other versions
- 【GPIO 1 INTO 2】: This expansion 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
- 【2 TYPE CONNECTIONS】: This 38Pin Development Board 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 and the circuit is stable and highly reliable, and there will be no poor circuit contact and unstable signal transmission
- 【UPDATED VERSION】: ESP32 Expansion Board 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

### ⭐⭐⭐⭐⭐ Perfect for prototyping ESP32 systems
*by R***Y on 30 June 2023*

Not sure why some reviews talk about pin spacing issues as my ESP32-WROOM-32D devices fit perfectly. Really good for wiring up the ESP32 in production mode with external power supplies for example and being able to unplug the ESP32 for re-programming without interfering with external power supplies, or to enable easy replacement in the field should the device fail in the future.

### ⭐ Wrong dimensions for associated ESP32 board
*by G***J on 29 December 2024*

In common with many other reviews, this board is wrongly sized for the associated ESP32 boards. Why does Amazon allow this issue to continue??? I have purchased this product on two occasions. First, in October 2024 the board was printed 0616. This board is fiune with all my ESP32 and lateral pitch between DIL rows is 25.8mm Sadly, although these boards appear to be electrically OK, they are warped. The second occasion produced boards printed "FOR ESP32 TERMINAL ADAPTOR" and having a pitch between rows of 23.7mm. These boards do not fit either of my ESP32 types, and certainly not the ESP32 boards with which they are linked, and sold. So - it seems there are two distinct types of boards, and those currently available are unsuitable. Really time that Amazon recognized thgis as a generic issue and did their own QC check
