SparkFun ESP8266 Thing. The reason for the popularity of many of these boards over the earlier ESP-xx modules is the inclusion of an on-board USB-to-UART bridge (like the Silicon Labs' CP2102 or the WCH CH340G) and a Micro-USB connector, coupled with a 3.3-volt regulator to provide both power to the board and connectivity to the host (software development) computer – commonly referred to as ...
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]

High-pin count (HPC), 400 I/O FPGA Mezzanine Card (FMC) connectors Top: mezzanine card side Bottom: baseboard side. FPGA Mezzanine Card (FMC) is an ANSI/VITA (VMEbus International Trade Association) 57.1 standard that defines I/O mezzanine modules with connection to an FPGA or other device with re-configurable I/O capability.
The de facto standard 8 inch FDD interface is based upon the Shugart Associates models SA800/801 [3] FDDs and models SA850/851 [4] FDDs. [5]: 171 The signal interface uses a dual in-line 50-pin PCB edge connector which mates to a flat ribbon cable connector; separate connectors are provided for both AC and DC power.
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 ...
Block diagram for a UART. A universal asynchronous receiver-transmitter (UART / ˈ juː ɑːr t /) is a peripheral device for asynchronous serial communication in which the data format and transmission speeds are configurable.
A registered jack (RJ) is a standardized telecommunication network interface for connecting voice and data equipment to a computer service provided by a local exchange carrier or long distance carrier.
