What is ESP8285?

ESP8285=ESP8266+1M Flash, the bearing high temperature is 125℃ (the one for ESP8266 is just 85℃). More important, the code programmed in ESP8266 can be used for ESP8285 intactly.

Introduction

• ESP-M2 is encapsulated by the high performance chip ESP8285, which is equal to ESP8266 chip plus 1M Flash. The chip ESP825 is encapsulated a advanced Tensilica’s L106 32-bit CPU, together with SRAM. ESP825 has the full and complete WiFi fuction, which can used independently and alsoused as a slaver with other Hoster MCU, which can start directly from the out-built Flash. In addition, the built-in high-speed buffer is 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.
