Sparkfun Electronics XBee Explorer Regulated

The SFE XBee Explorer Regulated takes care of the 3.3V regulation, signal conditioning and basic activity indicators (Power, RSSI and DIN/DOUT activity LEDs). It translates the 5V signals to 3.3V so that you can connect a 5V (down to 3.3V) system to any XBee module. The board was conveniently designed to mate directly with Arduino Pro boards and with the FTDI Basic boards for wireless bootloading and USB based configuration.
