AI-Thinker ESP-32S Wifi Bluetooth Combo Module

Note: If you need a larger quantity for your production, we also have this item as a full reel (800 pieces/reel).

The ESP-32S Wifi Bluetooth Combo module is based on the ESPRESSIF ESP32 chipset and offers best performance with low power consumption. The ESP-32S features a dual-core processor, 448 KByte ROM, 520 KByte SRAM, 16 KByte SRAM in RTC, 802.11 b / g / n / e / I Wi-Fi, Bluetooth v4.2 BR / EDR & BLE, clocks & times, peripheral interfaces and a security mechanism.

The module provides SDK firmware for fast online programming and open source toolchains based on GCC for development support. The module is designed for applications as low-power IoT sensor hub, logger, video streaming for cameras, Wi-Fi and Bluetooth enabled devices, home automation and mesh networking.

The ESP32 is a 2.4 GHz WLAN and Bluetooth combo chip developed with TSMC ultra low power 40 nm technology. The ESP32 is the most widely used Wi-Fi + Bluetooth solution in the industry and combines the antenna switch, RF balun, power amplifier, low-noise amplifier, filter and power management, so it takes up little space on the PCB.
