Product Description
The ESP-01 features a compact 2x4 pin header and an integrated PCB trace antenna. It is primarily used in two ways: as a WiFi adapter for other microcontrollers using Serial communication, or as a standalone controller for simple tasks like toggling a relay or reading a temperature sensor. Because of its 1MB flash memory, it can host small web servers or send data to cloud platforms like Blynk or ThingSpeak.
Key Features
Ultra-Compact Footprint: Measuring only 24.8mm x 14.3mm, it is ideal for space-constrained IoT devices and wearables.
Versatile Operating Modes: Supports Station (STA) mode to connect to a router, Access Point (AP) mode to create its own network, or a hybrid Dual Mode.
AT Command Set: Comes pre-flashed with firmware that allows you to control WiFi functions via standard Serial commands without complex coding.
Independent Programming: Compatible with the Arduino IDE and MicroPython, allowing you to bypass the AT commands and run custom firmware directly on the chip.
Low Power Capability: Supports sleep modes to conserve battery life in remote sensor applications.
