The newest version of the Xbee Shield is a standardized and stackable shield for Arduino. You can easily stack any modules from the Bee series and build a wireless network for your project! In spite of that, it is also equipped with the function of level conversion which enables a double-way conversion between high and low IO levels. The reversed digital pins facilitate users to select TX-RX ports using jumper caps.
