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 ...
The documentation shows the pin mapping of Arduino-naming to module pinout. Cuteduino: ATtiny85 Cytron Technologies: Cuteduino Features: ATtiny85 on board, 8 KB of flash, 512 byte of SRAM, 512 bytes of EEPROM. Internal oscillator runs at 16 MHz. USB bootloader so you can program it with the modified version Arduino IDE (from DigiSpark).
A "core" is the collection of software components required by the Board Manager and the Arduino IDE to compile an Arduino C/C++ source file for the target MCU's machine language. Some ESP8266 enthusiasts developed an Arduino core for the ESP8266 WiFi SoC, popularly called the "ESP8266 Core for the Arduino IDE". [18]

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 ...
For example, the device may take the signal on pin X, negate it, and output the result on pin Y. If the method of configuring a pin remains the same but the package of the device (such as TSSOP or QFN) changes, the program will continue to function but the physical locations of the pins the program works with may change.
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board. The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
They are used for embedded systems, chips (FPGA, ASIC, and SoC) and peripheral testing, programming and debugging. Many of them also provide scripting or programming capabilities (e.g. Visual Basic, C/C++, VHDL) and can be used with open source programs like flashrom, IMSProg, SNANDer or avrdude for flash, EEPROM, bootloader and BIOS programming.
