The ESP-32S WiFi Bluetooth Combo Module is a high-performance, low-power wireless platform built on the ESP32 chipset by ESPRESSIF. It integrates a dual-core processor, 448 KByte ROM, 520 KByte SRAM, and 16 KByte SRAM in RTC, along with 802.11 b/g/n/e/I Wi-Fi, Bluetooth v4.2 BR/EDR & BLE, clock and time functions, and various peripheral interfaces. With built-in security mechanisms, the ESP-32S is ideal for IoT applications, including sensor hubs, loggers, video streaming, home automation, and mesh networks.

This module comes with SDK firmware for fast online programming and open-source GCC-based toolchains for development. It is designed for low-power, high-performance applications, aimed at makers, hardware engineers, software engineers, and solution providers.

Built with TSMC’s ultra-low power 40nm technology, the ESP32 operates on a single 2.4 GHz Wi-Fi and Bluetooth chip optimized for power, RF performance, versatility, and reliability. It integrates multiple components, including the antenna switch, RF balun, power amplifier, low noise receive amplifier, filters, and power management modules, reducing the need for external parts and minimizing PCB space.

Designed for mobile, wearable, and IoT applications, the ESP32 features advanced low-power technologies such as clock gating, power modes, and dynamic power scaling, making it an excellent choice for various power profiles and wireless communication needs.
