ESP8285 ESP M1 built-in 1M byte for SPI Flash.
  • ESP-M1 / M2 module core processor using cost-effective chip ESP8285. 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.
 
Features
 
1) the volume is ultra-small;
2) serial to WiFi;
3) wireless transmission;
4) long-range ultra-low power consumption;
5) high temperature, up to 125 ℃
6) fully compatible with ESP8266, the source can be used to transplant.
