IoT Development Board Based On ESP-32S Module Supports WiFi And Bluetooth

Posted by Industry News on

HiLetgo ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA for Arduino IDE

The NodeMCU ESP-32S is an IoT (Internet of Things) development board created by NodeMcu to evaluate the ESP-WROOM-32 module. It is based on the ESP32 microcontroller that supports WiFi, Bluetooth, Ethernet, and Low Power support all in a single chip.

The NodeMCU-32S board is also an open source IoT platform. It uses Lua script and a lot of open source projects, such as lua-cjson, and spiffs. It contains firmware that can run on ESP32 WiFi SoC chips, and its hardware is based on ESP-32S modules. The ESP32 is a WiFi + Bluetooth chip developed by Shanghai Espressif, which aims to provide access network for embedded products.

The development board maintains the classic NodeMCU 1.0 design, with the I / O pins placed on either side of the board, which provides a more straightforward setup and breadboard use. Using a breadboard for development can simplify the use of this module by making use of both sides of the standard pin.

Open source, interactive, programmable, intelligent & straightforward, plus containing WIFI + Bluetooth hardware makes the NodeMCU ESP-32S a great little board to keep in your toolkit.

Internet of Things Projects with ESP32: Build exciting and powerful IoT projects using the all-new Espressif ESP32Internet of Things Projects with ESP32: Build exciting and powerful IoT projects using the all-new Espressif ESP32

The ESP32 is a low-cost MCU with integrated Wi-Fi and BLE (Bluetooth Low Energy). Various modules and development boards-based on the ESP32 are available for building IoT (Internet of Things) applications quickly. 

Wi-Fi and BLE are a standard network stack in the Internet of Things application. These network modules can leverage your business and projects needs for cost-effective advantages.

This book represents a significant guide for developing ESP32 software. We start with GPIO programming involving some sensor devices. 

Then we examine ESP32 development by building several IoT projects, such as weather stations, sensor loggers, smart homes, Wi-Fi cams, and Wi-Fi wardriving. 

Finally, we allow the ESP32 board to execute interactions with mobile applications and cloud servers such as AWS.

By the end of this book, you are up and running with various IoT projects based on the ESP32 chip.
