WBoard Pro is a Wifi development board based on Arduino MEGA. With a on-board ESP8266 chip (wifi firmware has been burnt in), you can drive ESP8266 to connect wifi and visit the internet by controlling the serial ports. WBoard Pro supports IoTgo Arduino Library to do a rapid development.

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.
