ESP8285 Development Board

The development board board Lexin ESP8285 ultra-low power UART-WiFi module and USB to TTL serial CH340 chip, can be easily developed for secondary development, access to cloud services, to achieve mobile phone 3/4G global control anytime, anywhere, accelerate Product prototype design. Based on the ESP8266, the ESP8285 integrates 1MB of Flash inside the chip to make it resistant to high temperatures up to 125 degrees Celsius! And the original ESP8266 source program can be used as it is.

The module core processor ESP8285 integrates the industry-leading Tensilica L106 ultra-low-power 32-bit micro MCU in a small package with 16-bit compact mode, 80MHz and 160MHz clock speed, RTOS support, and integrated Wi-Fi MAC/ BB/RF/PA/LNA supports the standard IEEE802.11 b/g/n protocol, complete TCP/IP protocol stack. Users can use this module to add to existing devices Networking capabilities can also build standalone network controllers.
The ESP8285 is a high-performance wireless SOC that offers maximum utility at the lowest cost, providing unlimited possibilities for WiFi functionality to be embedded in other systems. The ESP8285 is a complete, self-contained WIFI network solution that runs independently. The ESP8285 can be booted directly from an external flash memory when it is powered by the application and is the only application processor in the device. The built-in cache helps improve system performance and reduce memory requirements. It can also be used as a slave to be installed on other host MCUs.
