DOITING® ESP-M1/M2 User Mannual 1. Introduction The WiFi module ESP-Mx is manufactured by using a high-performance chip named 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 can be applied independently, and also 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.
