NodeM WIFI ESP8266 32M Flash CH340G Board (Not Solderd) RobotDYN

AED 45.00



The Wi-Fi NodeM ESP8266+extra memory module is a versatile and powerful development board based on the well-established ESP8266 System on Chip (SoC) from Expressif. This module has been enhanced with an additional memory size of 32Mb (Megabit), providing ample space for large projects and extensive libraries, eliminating concerns about memory limitations.



  1. Event-driven API: The module supports an event-driven API for network applications, enhancing the efficiency and responsiveness of your projects.
  2. USB-TTL Serial Converter CH340G: Equipped with an onboard USB-TTL serial converter (CH340G) and a Micro-USB socket, facilitating easy connectivity and programming.
  3. Power Options: The module can be powered through a DC power source in the range of 4 to 9V via the VIN pin, making it adaptable to various power supply configurations.
  4. Versatile I/O and Communication: It combines the features of a Wi-Fi access point and station with a microcontroller, supporting 10 GPIO pins (D0-D10), PWM functionality, IIC, SPI communication, 1-Wire, and ADC A0, providing extensive options for hardware I/O. This versatility allows for Arduino-like programming and is compatible with the Arduino IDE.
  5. Wi-Fi Networking: The module supports Wi-Fi 802.11 b/g/n in the 2.4 GHz band, enabling it to function as both an access point and station. It can host a web server and connect to the internet for data fetching or uploading.
  6. Development-friendly and Pin Headers: The module features pin headers with a spacing of 2.54mm (0.1") and 15 pins on 2 lines, allowing for easy connection without the need for soldering.
