NOTE:

  • J3
When jumpers connect both 2-4 and 1-3, CP2102 will connect to Mega2560’s UART0.
When jumpers connect both 4-6 and 3-5, CP2102 will connect to ESP8266’s UART0.
  • FW
Connect ESP8266’s GPIO0 to GND. If you want to burn the firmware into ESP8266, you should plug a jumper in FW. After reset ESP8266, you can start to burn the firmware into ESP8266.
  • E-RESET
Hard reset for ESP8266. Besides, ESP8266 RST pin connects to Mega2560 PC0 (Arduino D37). If you set PC0 pin low level, you can make a soft reset on ESP8266.
