Nodemcu ESP8285-M2 CH340

ESP8285 Based Nodemcu. IoT Development Module

This is a NodeMcu based on ESP8285 module. Yes not ESP8266 or ESP32 this module is based on ESP8285-M2 chipset.

The chip integrates the enhanced version of the Tensilica's L106 Diamond 32-bit core processor with on-chip SRAM in a smaller package. ESP8285 has a complete Wi-Fi network function, both can be used independently, can also be used as a slave from other host MCU running. When the ESP8285 hosting application, can be started directly from the external Flash. Built-in cache memory facilitates system performance and optimizes storage systems. In addition, ESP8285 only through the SPI / SDIO interface or I2C / UART port can be used as a Wi-Fi adapter, applied to any microcontroller-based design.

DNA Solutions has large collection of various types of ESP Wifi Module. Check our complete collection of ESP Wifi Module.
