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]
Other types are proprietary designations that may be made by only one or two manufacturers. Integrated circuit packaging is the last assembly process before testing and shipping devices to customers. Occasionally specially-processed integrated circuit dies are prepared for direct connections to a substrate without an intermediate header or carrier.
A symmetric layout of Charlieplexed LEDs. On left, 3 pins drive 6 LEDs arranged in a triangle. On right, 4 pins drive 12 LEDs arranged in a tetrahedron.. The Charlieplexing configuration may be viewed as a directed graph, where the drive pins are vertices and the LEDs are directed edges; there is an outward-pointing edge connected from each vertex to each other vertex, hence with n drive pins ...
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 ...
