2Pcs ESP8266 Development Board with 0.96-Inch OLED Color Display, Type-C to Serial Port CH340 Driver NodeMCU ESP-12E Module Pin Header Soldered for Ar-DUI-no IDE

The ESP8266 NodeMCU development board has a built-in 0.96-inch OLED display (128×64, SSD1306) and supports the I2C interface. It can be directly integrated without additional wiring, making it an ideal choice for quickly building ESP8266-based visual display projects
The development board is equipped with the ESP8266 ESP-12E module, using the Tensilica Xtensa 32-bit LX106 CPU (80-160MHz), equipped with 128KB RAM and 4MB Flash, which can provide stable performance for demanding ESP8266 IoT applications
The onboard OLED uses the I2C interface through the SDA (D6/GPIO12) and SCL (D5/GPIO14) pins on the ESP8266 NodeMCU, which can easily display real-time network status, sensor data, and other ESP8266 project information
