ESP-M2 ESP8285 Serial Wireless ,WiFi Transmission Module /มีหน่วยความจำ Flash 1M
– โมดูล Wifi ESP8285 เป็นรุ่นที่พัฒนาต่อจาก ESP8266 ภายในโมดูล ESP8285 = ESP8266 + 1M Flash
Introduction:
What is ESP8285?
ESP8285=ESP8266+1M Flash application temperature up to 125℃! First and foremost the code programmed in ESP8266 could be used for ESP8295 intact.
– ESP-M2 module core processor is the high-performance chip ESP8285, which is equal to ESP8266 chip plus 1M Flash.
– The chip ESP825 is encapsulated an advanced Tensilicas L106 32-bit CPU, together with SRAM. ESP825 has the full and complete WiFi function, which can be used independently and also used as a slave with other Hoster MCU, which can start directly from the out-built Flash. In addition, the built-in high-speed buffer is a benefit for the system performance. Especially, ESP8285 can be used as a WiFi adapter by SPI/SDIO and/or I2C/UART interface, when it is applied to the other MCU design.
