NodeMCU was created shortly after the ESP8266 came out. On December 30, 2013, Espressif Systems [6] began production of the ESP8266. [12] NodeMCU started on 13 Oct 2014, when Hong committed the first file of nodemcu-firmware to GitHub. [13]
The ESP8266 is a low-cost Wi-Fi microcontroller, with built-in TCP/IP networking software, and microcontroller capability, produced by Espressif Systems [1] in Shanghai, China. The chip was popularized in the English-speaking maker community in August 2014 via the ESP-01 module, made by a third-party manufacturer Ai-Thinker.
ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...
ESP8266, ESP8285: IEEE 802.11b/g/n: Tensilica Xtensa L106 (80 or 160 MHz) ESP8266: External only (up to 4 MiB) ESP8285: Internal only (1 or 2 MiB) 64+96 KiB: QFN32 ...
The unfortunate side to the ESP8266 (& hence, NodeMCU), is the lack of documentation from Espressif about the ESP8266 (a situation that has slowly been improving). Also, what defines a NodeMCU board as compared to other ESP8266 boards that happen to include a USB-to-TTL/UART bridge chip and a 3.3V regulator tied to the micro-USB 5V power supply ...
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
A low-power, wide-area network (LPWAN or LPWA network) is a type of wireless telecommunication wide area network designed to allow long-range communication at a low bit rate between IoT devices, such as sensors operated on a battery.
16 GPIO pins: Power: 3.3 VDC: The RTL8710 is a low-cost Wi-Fi chip with full TCP/IP stack and MCU (Micro Controller Unit) capability produced by Taiwanese ...
