ESP-M2 ESP8285 Wifi Module

ESP8285 M2 IoT Module with wifi interface

Basically an ESP8285 module is an ESP8266 Module with additional 1 MB of Flash memory and the ESP8285 can even bear high temperature upto 125℃ (the one for ESP8266 is just 85℃). More important, the code programmed in ESP8266 can also be used for ESP8285. 

The chip ESP825 is encapsulated an advanced Tensilica’s L106 32-bit CPU, together with SRAM. ESP825 has the full and complete WiFi function, which can be used independently and also used as a slave with other Hoster MCU, which can start directly from the out-built Flash. In addition, the built-in high-speed buffer is a benefit for the system performance. Especially, ESP8285 can be used as a WiFi adapter by SPI/SDIO and/or I2C/UART interface, when it is applied to the other MCU design.
