ESP32 (ESP WROOM 32) WiFi & Bluetooth Dual-Core MCU Module
The ESP32 WiFi and Bluetooth chip is the latest generation of Espressif products. It has a dual-core 32-bit MCU, which integrates WiFi HT40 and Bluetooth/BLE 4.2 technology inside.
Compared to the arduino ESP8266 (the previous generation), the ESP32 wifi and bluetooth chip (also known as ESP wroom 32) has a significant performance improvement. It is equipped with a high-performance dual-core Tensilica LX6 MCU. One core handles high speed connection and the other for standalone application development. The dual-core MCU has a 240 MHz frequency and a computing power of 600 DMIPS.
In addition, it supports Wi-Fi HT40, Classic Bluetooth/BLE 4.2, and more GPIO resources.
Engineered for mobile devices, wearable electronics and Internet of Things (IoT) applications, the ESP32 wroom 32 achieves ultra-low power consumption with a combination of several proprietary software applications. The state-of-the-art power saving features include fine resolution clock gating, power modes, and dynamic power scaling.
