ESP-01/ESP-01S Breadboard Adapter – Mini Breakout Board for ESP8266 WiFi Module

Description

Product Overview

The ESP-01/ESP-01S Breadboard Adapter is an essential accessory for anyone working with the popular ESP8266 WiFi modules. This mini breakout board solves the fundamental challenge of using the ESP-01 module with standard prototyping platforms: its 2×4 pin header does not fit directly into a breadboard. This adapter converts the compact DIP-8 layout into a standard 0.1-inch (2.54mm) pin spacing that is fully compatible with breadboards, perfboards, and standard development boards .

Designed specifically for the ESP-01 and ESP-01S modules, this breakout board provides a stable, reliable platform for prototyping your IoT projects. The module simply plugs into the adapter board, which then provides clear access to all eight pins arranged in a standard 8-pin DIP format . This simple solution eliminates the need for messy jumper wires, reduces connection errors, and provides a professional foundation for your wireless projects .

Whether you are a hobbyist developing smart home devices, an educator teaching IoT concepts, or a professional prototyping wireless sensors, this breadboard adapter is an indispensable tool that saves time, reduces frustration, and ensures reliable connections.

Key Features

• Direct ESP-01/ESP-01S Compatibility: Designed specifically for the ESP-01 and ESP-01S WiFi modules. The adapter accepts the module’s 2×4 pin header directly, providing a secure mechanical and electrical connection .

• Standard 0.1″ Pin Spacing: Converts the module’s compact DIP-8 layout into standard 2.54mm (0.1-inch) pin spacing, making it fully compatible with standard breadboards, perfboards, and PCB sockets .

• Plug-and-Play Design: No soldering required for the ESP module connection. Simply plug your ESP-01 into the adapter’s female headers, and then plug the adapter into your breadboard or prototyping platform .

• Clear Pin Labeling: Each pin is clearly labeled on the adapter board, eliminating guesswork and reducing wiring errors. Pin assignments include VCC, GND, GPIO0, GPIO2, TXD, RXD, RST, and CH_PD/EN .

• Dual ESP-01/ESP-01S Support: Compatible with both the original ESP-01 (blue PCB) and the updated ESP-01S (black PCB) modules. The adapter accommodates the slight variations between these versions .

• Compact and Lightweight: The adapter board is sized to minimize footprint on your breadboard, leaving ample space for other components and wiring .

• Robust Construction: Built with high-quality FR4 PCB material and precision-milled pin headers for reliable, long-lasting connections .

• Gold-Plated Pins (Select Models): Some versions feature gold-plated pins for improved corrosion resistance and superior conductivity .
