Project Description

The requirement was to design a USB to Multi-protocol wireless converter, that is capable of converting a USB port to most popular wireless communication protocols. We designed the converter as a general propose USB to UART converter with pinout for the popular XBee modules, as well as for the popular HC-XX Bluetooth modules. This board can be used with all wireless modules that are pin compatible with the XBee modules. The board also has a 3 pin UART header that can be used with modules that are not pin compatible with the XBee modules. The board is completely USB powered and does not need any additional power. An on-board LDO switching regulator converts the USB bus voltage to the 3.3V to match the modules power requirement.
