Description ESP8266 Development Board with 0.96-inch OLED Display, CH-340 Features: 1. This is an ESP8266 0.96-inch OLED board with all the functionality of a standard ESP8266 module. 2. Seamless integration with 0.96-inch OLED displays eliminates the need for cables and test boards. 3. The board uses I2C to connect to the OLED display via the SDA (D6/GPIO14) and SCL (D5/GPIO12) pins. 4. The module includes a display template for displaying various information and data. 5. The high-resolution 128x64 display with SSD-1306 driver is compatible with I2C and SPI interfaces and can be connected via USB-C. Product Introduction: This board integrates the ESP8266 NodeMCU and a 0.96-inch OLED display. It offers all the functionality of conventional ESP8266 modules in the same size and with the same peripheral connections, plus more powerful development tools and a high-resolution data display. It supports various programming modes and features an ESP8266 chip with an 80 MHz clock speed and 4 MB of flash memory. This allows it to easily handle diverse tasks and applications. It also offers a full network protocol stack and security mechanisms. Thanks to its low power consumption and high performance, it is suitable for both beginners and professionals for developing and implementing IoT projects. Parameters: Operating voltage: 3.3 V, Input voltage: 7–12 V, Digital inputs/outputs (DIO): 16, Analog inputs (ADC): 1, UART: 1, SPI: 1, 12Cs: 1, Driver: CH340G, Flash memory: 4 MB, SRAM: 64 KB, Clock speed: 80 MHz, Color: Black, Material: Printed circuit board + electronic components. Depending on the batch, the printed batch code symbol may vary. However, this does not affect the contents of the package: 1 x development board, 2 x pin headers. Only the above-mentioned package contents are included; other products are not included. Note: Light reflections and different screen settings may cause the color of the item in the picture to differ slightly from the original. The allowable measurement deviation is +/- 1-3 cm.
