## Overview

This 2-piece ESP32 breakout board set features a 38-pin double-layer PCB designed specifically for the ESP-WROOM-32 microcontroller. It expands one GPIO pin into two, supports dual connection types (pin headers and screw terminals), and comes fully soldered for immediate use. Ideal for professional-grade smart home projects, it offers stable signal transmission and compact compatibility, empowering developers to build sophisticated wireless IoT solutions with WiFi and Bluetooth capabilities.

## 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: Good for the money. - Got these as the breadboard on my current project was getting really messy. Don't think they'd last too long with repeated use as a prototyping board but as a permanent solution they're fine. Headers for the ESP32 are solid and line up perfectly and terminal blocks are okay. No problems with shorts or dodgy connections. I'm using 1.5mm multicore wire on some of the connections which is a snug fit but that's overkill on my part. All in all, very pleased for the money.

## 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

### ⭐ 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
