The 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.
This unit works with all XBee modules including the Series 1 and Series 2.5, standard and Pro versions. Plug an XBee into this breakout and you will have direct access to the serial and programming pins on the XBee unit and will be able to power the XBee with 5V. Wow there are a lot of XBee modules! Here's a breakdown:
You get the red board only. XBee modules sold below.
