DOIT Mini Ultra-Small size ESP-M3 Serial WiFi Module Compatible with ESP8266

The DOIT Mini Ultra-Small size ESP-M3 Serial WiFi Module is manufactured by using a high-performance chip ESP8285. This small chip is encapsulated an enhanced Tensilicas L106 Diamond series 32-bit kernel CPU with an SRAM. Thus, ESP8285 has the complete function of Wi-Fi function; it not only can be applied independent but can be used as a slave working with other host CPU. When ESP8285 is applied as a slave, it can start from the onboard Flash. The built-in high-speed buffer is not only benefiting improve the system performance but optimizing the store system. In addition, ESP8285 can be used as a Wi-Fi adapter by SPI/SDIO or I2C/UART interface, when it is applied to other MCU design. Features: Ultra-small size. Support serial to WiFi Wireless transparent transmission. Long-distance transmission with ultra-low power. Support outboard antenna. Bearing high temperature to 125 C, compared to the 85C for ESP8266. Module size:24.5mm x 14mm. Derived from ESP8266, ESP8285 has a flash memory of 1MB Totally compatible with ESP8266 WiFi support 802.11 b/g/n/e/i High temperature resistant, working temperature: -40-125 SOC characteristics: Built-in Tensilica L106 ultra-low power consumption 32-bit CPU, the main frequency can be 80MHz and 160MHz, also support RTOS; Built-in TCP/IP protocol stack; Built-in 1 channel 10-bit high precision ADC; The outside interfaces have HSPI, UART, I2C, I2S, IR Remote Control, PWM, GPIO; The deep-sleep current is about 10uA, and the cut-off current is smaller than 5uA; Can be wake-up within 2 ms, and connect to transmit data package; the consumer power is smaller than 1.0mW (DTIM3) when at standby status; built-in 1M byte for SPI Flash.
