Description ESP-32S is a powerful, generic WiFi-BT-BLE MCU module that targets a wide variety of applications ranging from low power sensor networks to the most demanding tasks such as voice encoding, music streaming and MP3 decoding. At the core of this module is the ESP32 chip, which is designed to be scalable and adaptive. There are 2CPU cores that can be individually controlled or powered, and the clock frequency is adjustable from 80 MHz to 240 MHz. The user may also power off the CPU and make use of the low power coprocessor to constantly monitor the peripherals for changes or crossing of thresholds. ESP32 integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, low noise sense amplifiers, SD card interface, Ethernet, high speed SDIO/SPI, UART, I2S and I2C. The integration of Bluetooth, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted,and that it is future proof: using Wi-Fi allows a large physical range and direct connection to the internet through a Wi-Fi router, while using Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection. The sleep current of the ESP32 chip is less than 5 µA, making it suitable for battery powered and wearable electronics applications. ESP-WROOM32 supports data rates up to 150 Mbps, and 22 dBm output power at the PA to ensure the widest physical range. As such the chip does offer industry leading specifications and the best optimized performance for electronic integration, range and power consumption, and connectivity.

Product Specification Model NumberESP8266-01BrandESPWeight12gDimension49 x 24.5 x 13mmApplicationDATA TransmissionOperating Temperature40 deg C~125 deg C Product DescriptionESP8266 WiFi module is WiFi serial transceiver module, based on ESP8266. Small size and low cost makes it suitable for sensor nodes. It works on 3.3V and consumes current up to 250mA. Current consumption is quite big so it''s usually not powered on battery. If you are using 5V Arduino, then read ESP8266 WiFi and 5V Arduino connection

For arduino board we will use Arduino pro mini 3.3V 8Mhz and software serial port. HW serrial port will be available for program uploading and debugging. Later you can switch module to HW serial port.

Before we start using ESP8266 WiFi module we need to update ESP8266 firmware. We use V0.9.2.2 version of firmware. Detail instructions how to update firmware can be found here. New firmware default baudrate is 9600 which makes possible to use software serial on Arduino board.

ESP8266 current consumption is too big to use Arduino internal regulator. We will use dedicated power regulator AMS1117. Make sure to use big enough additional capacitors to prevent voltage drops when transmitting.

This is WiFi serial transceiver module, based on ESP8266 SoC. This is the ESP-01 VariantThis has an integrated tcp/ip stack ESP8266 is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area. The Module Comes with a default AT Firmware. Download the AT Documentation ### This module comes with No Support from us as of the Moment. However There are plenty of Resources Online. So Buy This only if you know what you are getting into

Product Description"NodeMCU" is an open source IoT platform. It includes firmware which runs on the ESP8266 Wi-Fi SoC from Espressif Systems, and hardware which is based on the ESP-12 module. The term “NodeMCU” by default refers to the firmware rather than the DevKit. The firmware uses the Lua scripting language. NodeMCU is based on the eLua project, and built on the Espressif Non-OS SDK for ESP8266. NodeMCU uses many open source projects, such as lua-cjson, and spiffs.
