Product Introduction
The core processor of the ESP-M1/M2 module uses the cost-effective ESP8285 chip. The ESP8285 offers complete Wi-Fi networking functionality — it can operate independently, or serve as a slave device paired with another host MCU. The ESP8285 only requires an SPI/SDIO interface or an I2C/UART port to function as a Wi-Fi adapter, making it applicable to designs based on any microcontroller.
