ESP32(ESP-WROOM-32) WiFi Bluetooth Dual-Core MCU Module

INTRODUCTION
 

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 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.

ESP32 chip integrates a wealth of hardware peripherals, including capacitive touch sensors, Hall sensors, low noise sensor amplifiers, SD card interfaces, Ethernet interfaces, high-speed SDIO / SPI, UART, I2S and I2C, etc.

Support Arduino Programming

Engineered for mobile devices, wearable electronics and Internet of Things (IoT) applications, the ESP32 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.

DFRobot introduces the ESP-ROOM-32 module, based on the Espressif. ESP32 chip. It has integrated electronic peripherals, external expansion of all GPIO pins, an onboard antenna, stamp hole design and easy mass production. It can be used for product development, integrated design and many more applications.
