Mini ESP-M3 ESP8285 Breakout Board

Features

• ESP8285 = ESP8266 + 1M Flash
• Can withstand high temperatures up to 125 degrees Celsius!
  
• If you have any existing NodeMCU Lua ESP8266 source code programs, they can be used directly
• Applications can be started directly from the external Flash
• Built-in cache memory facilitates system performance and optimizes storage
• Can also be used as a standalone serial Wifi Module for use with Arduino UNO or other microcontrollers accessed only through the SPI / SDIO interface or I2C / UART ports
• Uses CH340 chip (requires driver download)
  
• Code build from: https://github.com/micropython/micropython
