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 ...
Includes 14 color-coded 3-pin connectors for direct cable connection of servos, electronic bricks, etc., and 6 color-coded3-pin connectors to Analog inputs for electronic bricks, etc. Provides improved 3.3 V regulator supplying 500 mA, and optional 3.3 V operation. Switching regulator provides 5 V 2 A from up to 20 V external supply.
A GPIO pin's state may be exposed to the software developer through one of a number of different interfaces, such as a memory-mapped I/O peripheral, or through dedicated IO port instructions. Some GPIOs have 5 V tolerant inputs: even when the device has a low supply voltage (such as 2 V), the device can accept 5 V without damage.
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]

A line that is an output on a DTE device is an input on a DCE device and vice versa, so a DCE device can be connected to a DTE device with a straight wired cable, in which each pin on one end goes to the same numbered pin on the other end. Conventionally, computers and terminals are DTE, while peripherals such as modems are DCE.
EEPROM or E 2 PROM (electrically erasable programmable read-only memory) is a type of non-volatile memory. It is used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems , or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and ...
Though 3rd-party boards have similar board names it doesn't automatically mean they are 100% identical to official Arduino boards. 3rd-party boards often have a different voltage regulator / different USB-to-UART chip / different color solder mask, and some have a different USB connector or additional features, too.
