Node MCU ESP8266 with CP2102 USB-Serial InterfaceThe development board has an ESP 12E module with an ESP8266 chip with a Tensilica Xtensa 32 bit LX106 RISC CPU that supports RTOS and runs at 80 to 160 MHz configurable clock frequency. There's also 128 KB of RAM and 4MB of Flash memory (for Applications and data storage), which is more than adequate to handle the enormous strings that create web pages, JSON XML data, and everything else we want in IoT devices these days. Features Built in Micro USB,

74HCT series ICs are High-speed logic gates with very low power consumption that utilize advanced silicon-gate CMOS
