ESP8285 test board description:

  • This board is suitable for firmware burning test of Essen and our ESPM1, ESPM2, ESP01S, ESP01 and other modules.
  • All IO ports have been exported and can be used as smallest system development boards or small batch burning fixtures. The board supports firmware one-click download function and adds programming
  • Mode indicator (blue light) and serial communication indicator (green light).
  • ESP8285=ESP8266+1M Flash. Compared with the ESP8266, it can withstand temperatures up to 125 degrees Celsius! And the original ESP8266 source program can be used as it is.


ESP-M2 wifi module features:

  • Ultra-small size;
  • Serial to WiFi;
  • Wireless transparent transmission;
  • Long distance ultra low power consumption;
  • An external antenna can be used.
  • High temperature resistance up to 125°C
  • Fully compatible with ESP8266, the source code can be directly ported.
  • The ESP-M2 module core processor 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, and can be applied to any microcontroller-based design.
