ESP32 WiFi Bluetooth MCU Module / ESP-WROOM-32

The ESP-WROOM-32 is a powerful universal WiFi-BT-BLE MCU module for a variety of applications, from low-power sensor networks to the most demanding tasks such as voice coding, music streaming and MP3 decoding. ESP8266 bringing WiFi to a small and cheap package, but also has enough processing power and enough pins to complete the small things and began a small revolution.

Now you can use the ESP-WROOM-32 WiFi / Bluetooth Classic / BLE module to elevate your WiFi capabilities to a higher level! The product is just a module - it could be hard to use. You need to solder it on a board with support circuit (see Espressif's assembled ESP32 development board for a more complete design). This module is currently available for use by developers, FCC, CE, IC, MIC (Telec), KCC and NCC certifications.

The ESP-wroom-32 module totally fits for WiFi 802.11b/g/n/e/i and Bluetooth v4.2 BR/EDR & BLE standard, and providing a series of solutions of Wifi and Bluetooth to support open real-time operating systems (RTOS). it also offers an open platform to support users to custom function flexibly in various applications.

Espressif Systems have their headquarters based in Shanghai Zhangjiang High-Tech Park, which is considered to be “China’s Silicon Valley”, where they produce low-power WiFi and Bluetooth SoC’s and IoT hardware and software.

Their vision is to enhance the world by leveraging modern technologies like IoT and wireless communications to manufacture products that are more versatile, adaptable and eco-friendly, with the aim of reducing the amount of waste and pollution that the world produces each year. So far, they have been able to reduce the consumption of electrical components by hundreds of thousands of resistors, capacitors, inductors, baluns, switches and power management chips, while reducing the amount of Printed Circuits Boards, or PCB’s, by more than 50,000 square meters.

Espressif is quickly becoming the leading manufacturer of IoT and wireless components, modules and devices that cut out the need for cabling and unnecessary electronics, which will not only result in a world that is cleaner and more environmentally sustainable, but also more adaptable and capable of moving towards the future of human technologies.
