Keyestudio ESP-01S Wifi Module Adapter Board for Arduino ESP8266 WIFI

The Keyestudio ESP-01S WiFi Module Adapter Board is a compact expansion board designed to make breadboard prototyping with the ESP-01S module effortless. It is ideal for South African students, hobbyists, and makers looking to integrate wireless connectivity into their Arduino projects. By breaking out the pins to a standard pitch, it simplifies your circuit building and minimises messy wiring.

Breadboard friendly design

This adapter board plugs directly into standard breadboards, breaking out the ESP-01S module pins for easy prototyping. It resolves the awkward pin pitch of the standard module, allowing for rapid circuit building.

Clear alignment indicators

The board features a clear arrow silk-screen indicator to ensure you insert your ESP-01S module in the correct orientation. This simple visual guide helps prevent connection errors and protects your hardware.

Instant AT command testing

Upon powering up, the module automatically enters BOOT flash mode. This allows you to perform AT command tests immediately without needing to configure complex manual switches.

Compact and lightweight footprint

Measuring just 18.8mm by 16.8mm by 19.8mm and weighing only 2.3g, this board adds minimal bulk to your projects. It is an ideal choice for space-constrained IoT applications and neat custom enclosures.

Power and communication specifications

The adapter operates on a 5V DC working voltage with a minimum current requirement of 500mA. It features a 3.3V communication voltage level and carries ROHS environmental certification.
