AI-Thinker ESP32-S Wi-Fi + Bluetooth 4.2 SoC Module w/ PCB Antenna

Description

The AI-Thinker ESP32-S module is a fully integrated wireless SoC solution built around the Espressif ESP32 chipset. It combines a high-performance dual-core microcontroller with comprehensive Wi-Fi and Bluetooth 4.2 radio stacks, all housed in a shielded SMD-38 package for reliable RF performance. The module comes pre-loaded with AT command firmware for immediate UART-based network control, while its open SDK support enables custom firmware development in Arduino, ESP-IDF, or MicroPython environments.

Engineered for low-power IoT deployments, the ESP32-S features advanced power management with multiple sleep modes, enabling extended operation in field applications. Its integrated 32Mbit SPI flash provides ample storage for application code and file systems. The module’s 3.0-3.6V operating voltage range and robust peripheral interface set make it a foundational component for scalable smart home, industrial automation, and wearable device designs requiring reliable wireless connectivity.
