USB to UART adapter
This is an adapter which allows easy communication with a micro controller or any other UART device from the USB port of a computer. It uses the popular and widely supported FT232 USB to UART converter from FTDI. The pin spacing is standard 0.100" and will accept a four pin header so that it can be plugged directly into a breadboard. The pinout is labeled on the board and is +5v, TX, RX, and GnD. The adapter is powered from the USB side and the +5v and GnD pins are directly connected from the USB connector with no over current protection.
