AI-Thinker ESP-01S ESP8266 WiFi Module

Description

The ESP-01S module from AI-Thinker encapsulates the full capabilities of the ESP8266EX system-on-chip into a minimal-footprint board. It functions as a self-contained SOC with an integrated LWIP TCP/IP stack, capable of hosting an application or offloading all Wi-Fi networking functions from a primary host microcontroller via simple serial AT commands.

Designed for cost-effective IoT integration, its high on-chip integration minimizes external RF circuitry requirements. The module supports advanced features like APSD for VoIP and Bluetooth co-existence interfaces, backed by a self-calibrated RF system that ensures stable operation across varying environmental conditions.
