Description The WiFi module ESP 1 is manufactured by using a high performance chip ESP8285 This small chip is encapsulated an enhanced Tensilicas L106diamond series 32 bit kernel CPU with a SRAM Thus ESP8285 has the complete function Wi Fi function it not only can be applied independent but can be usedas a slaver 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 Wi Fi adapter by SPI SDIO or I2C UART interface when it is applied to other MCU design More details please visit this GitHub link to get the manual and tools https github com Smart SZDOITWiKi wiki ESP8285 ESP 1 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 ℃ compared to the 85℃ for ESP8266 Working temperature 40℃ 125℃Module size 24 5mm 14mm SOC characteristics Built in Tensilica L106 ultra low power consumption 32 bit CPU the main frequency can be80MHz 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
