New earth robotics Store are happy to stock the fantastic XBee Explorer USB.
With so many on offer recently, it is great to have a name you can recognise. The XBee Explorer USB is certainly that and will be a excellent purchase.
For this price, the XBee Explorer USB is widely respected and is always a popular choice for many people. SparkFun Electronics have included some excellent touches and this results in good value for money.
This is a simple to use, USB to serial base unit for the Digi XBee line. This unit works with all XBee modules including the Series 1 and Series 2.5, standard and Pro version. Plug the unit into the XBee Explorer, attach a mini USB cable, and you will have direct access to the serial and programming pins on the XBee unit.
The highlight of this board is an FT231X USB-to-Serial converter. That's what translates data between your computer and the XBee. There's also a reset button, and a voltage regulator to supply the XBee with plenty of power. In addition, there are four LEDs that'll help if you ever need to debug your XBee: RX, TX, RSSI (signal-strength indicator), and power indicator.
This board also breaks out each of the XBee's I/O pins to a pair of breadboard-compatible headers. So if you want to make use of the XBee's extended functionality, you can solder some header pins into those, or even just solder some wire.
Note: There is no XBee included with this Explorer USB.
