برد توسعه NodeMCU-32S با هسته ESP-WROOM-32 دارای بلوتوث و وایفای داخلی

NodeMCU is an open-source networking platform. It uses the Lua scripting language. The platform is based eLua open source project. "NodeMCU-32S" is based on ESP-32S module. The platform uses a lot of open-source projects, such as lua-cjson, spiffs. "NodeMCU-32S" can run on chips ESP32 Wi-Fi SoC firmware and hardware module based on ESP-32S. ESP32 is developed by Shanghai Espressif WiFi + Bluetooth chip designed for embedded products that provide network coverage. The ESP32 series employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, with a clock rate, up to 240 MHz. It is designed to achieve the best power and RF performance, showing robustness, versatility, and reliability in a wide variety of applications.

It features all the state-of-the-art characteristics of low-power chips, including fine-grained clock gating, multiple power modes, and dynamic power scaling. For instance, in a low-power IoT sensor hub application scenario, ESP32 is woken up periodically and only when a specified condition is detected. A low-duty cycle is used to minimize the amount of energy that the chip expends. The output of the power amplifier is also adjustable, thus contributing to an optimal trade-off between communication range, data rate, and power consumption.
