ESP8285 WiFi module ESP-M3

Description :

AT firmware:

This firmware only supports AT commands to operate the module.

Transparent transmission firmware:

This firmware configures the module through the web page, similar to the router configuration

 What is the ESP8285?

· ESP8285=ESP8266+1M FlashTo make it resistant to high temperatures125 degrees Celsius!And the original ESP8266 source program can be used as it is..

· The core processor of the ESP-M3 module uses the cost-effective chip ESP8285. The chip integrates an enhanced version of Tensilica's L106 Diamond Series 32-bit core processor in a smaller package with on-chip SRAM. The ESP8285 has a full Wi-Fi network function, which can be used independently or as a slave to other host MCUs. When the ESP8285 hosts an application, it can be launched directly from external Flash. The built-in cache helps improve system performance and optimizes the storage system. In addition, the ESP8285 can be used as a Wi-Fi adapter via the SPI/SDIO interface or I2C/UART port for any microcontroller-based design.

1) The volume is too small;

2) Serial port to WiFi;

3) Wireless transparent transmission;

4) Ultra-low power consumption over long distances;

5) high temperature resistance up to 125 ° C;

6) Fully compatible with ESP8266, the source code can be used as it is.
