Description of product


The ESP-M1 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. ESP8285 has a complete of Wi-Fi mesh network capabilities, both to standalone application , or as a slave mounted on another host MCU running . 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.
