Description:

The NodeMCU CP2102 is a development board based on the ESP8266 WiFi module. The CP2102 is a USB-to-UART bridge chip that enables communication between the ESP8266 module and a computer through the USB interface. The NodeMCU development boards are widely used for IoT (Internet of Things) projects due to their built-in WiFi capabilities.

Features:

1. ESP8266 Module:
• The NodeMCU CP2102 is built around the ESP8266 WiFi module, which provides WiFi connectivity for IoT applications.
2. CP2102 USB-to-UART Bridge:
• The CP2102 chip facilitates USB communication between the NodeMCU board and a computer.
3. GPIO Pins:
• The NodeMCU board has multiple GPIO (General Purpose Input/Output) pins that can be used for connecting sensors, actuators, or other peripherals.
4. USB Micro-B Port:
• It comes with a USB Micro-B port for programming and power supply.
5. Onboard Voltage Regulator:
• The onboard voltage regulator allows the NodeMCU board to be powered using a USB connection.
6. Lua Script Interpreter:
• NodeMCU firmware is often used on these boards, providing a Lua script interpreter for easy programming.

Pinout:

The pinout of the NodeMCU CP2102 includes GPIO pins, power pins, ground, and other essential connections. The specific pin mapping can vary slightly depending on the NodeMCU version, so it's essential to refer to the documentation or silk screen on the board.

Here's a general idea of the pinout:

• TX and RX: Serial communication pins.
• D0 to D8: Digital GPIO pins.
• A0:Analog input pin.
• 3V3 and 5V: Power supply pins.
• GND: Ground.
