Introduction

The WiFi module ESP-M1 is manufactured by using a high-performance chip named ESP8266. This small chip is encapsulated an enhanced Tensilica’s L106 diamond series 32-bit kennel CPU with a SRAM. Thus, ESP8266 has the complete function Wi-Fi function; it can be applied independently, and also can be used as a slaver working with other host CPU. When ESP8266 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, ESP-M1 WiFi module can be used as Wi-Fi adapter by SPI/SDIO or I2C/UART interface, when it is applied to other MCU design. The ESP-M1 WiFi 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 an independent network controller. Anyway, ESP-M1 module provides many probabilities with the best price.
