What it does

The ESP8266 NodeMCU CP2102 WiFi Module IoT Development Board offers reliable WiFi connectivity with the premium CP2102 USB bridge. Perfect for IoT projects requiring stable serial communication and robust WiFi performance.

Key features

  • 802.11 b/g/n WiFi with integrated TCP/IP stack
  • CP2102 USB-to-UART bridge for reliable programming
  • Low power consumption with deep sleep modes
  • Multiple GPIO pins with PWM, I2C, SPI support
  • Full Arduino IDE support with ESP8266 core
  • 4MB flash memory for application storage
  • Micro-USB connector for power and programming

Good to know

  • All GPIO operate at 3.3V logic – use level shifters for 5V
  • Install CP2102 driver from Silicon Labs if needed
  • GPIO0 must be LOW during boot for programming mode
  • Install ESP8266 board package in Arduino IDE
  • CP2102 generally more reliable than CH340 for serial communication
