NodeMCU Development Board Pinout Configuration
| Pin Category | Name | Description |
| Power | Micro-USB, 3.3V, GND, Vin | Micro-USB: NodeMCU can be powered through the USB port
3.3V: Regulated 3.3V can be supplied to this pin to power the board
GND: Ground pins
Vin: External Power Supply |
| Control Pins | EN, RST | The pin and the button resets the microcontroller |
| Analog Pin | A0 | Used to measure analog voltage in the range of 0-3.3V |
| GPIO Pins | GPIO1 to GPIO16 | NodeMCU has 16 general purpose input-output pins on its board |
| SPI Pins | SD1, CMD, SD0, CLK | NodeMCU has four pins available for SPI communication. |
| UART Pins | TXD0, RXD0, TXD2, RXD2 | NodeMCU has two UART interfaces, UART0 (RXD0 & TXD0) and UART1 (RXD1 & TXD1). UART1 is used to upload the firmware/program. |
| I2C Pins | NodeMCU has I2C functionality support but due to the internal functionality of these pins, you have to find which pin is I2C. |
