ESP8285 ESP M1
Because of the ultra-small size, ESP-M1/ESP-M2 is now very popular for many people. Moreover, this two modules are based on ESP8285 chip. Compared to the previous modules (e.g., ESP-F, ESP-S, and ESP-E), which are based on ESP8266 chip, the differeces are obvious and listed as follows.
- Small size;
- Bearable a higher temperature (about +125℃), but ESP8266 is just +85℃;
- The original ESP8266 code can be used on this modules (based on ESP8285, DO NOT change any code);
- Support serial transpent transmission;
- Support long distance with ultra-low power;
- Support a onboard antenna (For ESP-M1).

The WiFi module ESP-M is manufactured by using a high-performance chip ESP8285. This small chip is encapsulated an enhanced Tensilica’s L106 diamond series 32-bit kennel CPU with a SRAM. Thus, ESP8285 has the complete function Wi-Fi function; it not only can be applied independently, but can be used as a slaver working with other host CPU. When ESP8285 is applied as a slaver, it can start from the onboard Flash. The built-in high-speed buffer is not only benefit to improve the system performance, but optimize the store system. In addition, ESP8285 can be used as Wi-Fi adapter by SPI/SDIO or I2C/UART interface, when it is applied to other MCU design. The ESP-M module supports the standard IEEE802.11 b/g/n/e/i protocol and the complete TCP/IP protocol stack. User can use it to add the WiFi function for the installed devices, and also can be viewed as a independent network controller. Anyway, ESP-M module provides many probabilities with the best price.
