Introduction to NodeMCU V3. NodeMCU V3 is an open-source firmware and development kit that plays a vital role in designing your own IoT product using a few Lua script lines. Multiple GPIO pins on the board allow you to connect the board with other peripherals and are capable of generating PWM, I2C, SPI, and UART serial communications.GPIO9 and GPIO10: ESP8266 uses an external FLASH memory chip and communicates with it with a 4-bit SDIO interface. These two pins are on the list. By default, both are used in this But it is possible to set it to 2-bit mode and release these two pins. You gain in the number of pins, but you lose in memory access speed.According to the Arduino website: "The Arduino IDE 2.0 is an improvement of the classic IDE, with increased performance, improved user interface and many new features, such as autocompletion, a built-in debugger and syncing sketches with Arduino Cloud".
