Bridge Series based on Arduino is a totally new and extremely hot product series, released by ElecFreaks in 2013. Some of them are compatible to Arduino interface, and some others are designed for unique development environments. They are highly characteristic by the bridging role, bridging wireless communications, bridging to the Internet, bridging to various interfaces such as XBee, RF, SD card, NFC, WIFI and so on.
WR Bridge V1.1 is a very unique Arduino board, mainly composed of SIM900 GSM / GPRS module, XBee socket, nRF24L01 + module, SD interface relay control module and ATMega328 control module.

Bridge series does't have USB port for compiling, and you must use the provided UART interface. Of course, you can also choose to use the normal USB Adapter for compiling, but you must make sure of your USB Adapter with DTR signal pin. Due to this, we recommend the ElecFreaks Bluetooth Bee USB Adapter, which can perfectly function together with NX-bridge. Besides, Bee adapter itself is also very powerful, supporting both XBee and Bluetooth bee interfaces at the same time.
