The Doit Company produced this Nodemcu-M. It works flawlessly with the Nodemcu V3. With just a few lines of Lua code, you can rapidly develop your IoT product using the open-source NodeMcu firmware and development kit. ESP8285 is made up of an ESP8266 and a 1M Flash chip, and it can endure temperatures of up to 125 degrees Celsius. Additionally, the ESP8266 source code can be utilized just as is. The ESP8285 chip serves as the ESP-M2 module's core CPU. The device incorporates an improved L106 Diamond Series 32-bit core processor from Tensilica into a more compact packaging with on-chip SRAM. Full Wi-Fi networking capabilities are available on the ESP8285, which may be utilized both independently and as a slave to additional host MCUs. When the ESP8285 hosts an application, it can be launched directly from external Lightning. The built-in cache helps improve system performance and optimizes the storage system. Additionally, the ESP8285 can be used as a Wi-Fi adapter via the SPI/SDIO interface or I2C/UART port for any microcontroller-based design.
