Overview
WBoard EX is a unique Arduino board with WIFI module, XBee socket, nRF24L01 + module interface, micro SD card interface, electronic brick interface and ATmega32U4 chip. WBoard EX boot procedure is based on Arduino Leonardo. With WIFI module, the board can achieve wireless communication with TCP / IP protocol. Via XBee and nRF24L01 + or WIFI can be used for wireless control with functions covering from smart home to remote control to meet various needs of different projects.
