The XBee to USB Adapter is an usefull tool that allows to connect Personal Computers or a microcontroller in wireless networks using the famous XBee wireless modules.
This bi-directional logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V at the same time. This level converter also works with 2.8V and 1.8V devices, with a total of four signals.
This board is usefull to convert the RS-232 PC Serial Port signals to logic level datas used in any digital board that uses a serial port with 3.3V or 5V level lines.
