USB-TTL FTDI232 6pin 3.3/5V

This USB to TTL serial adapter is ideal for many uses, including:
- Programming microprocessors such as ARM, AVR, etc
- Working with computing hardware such as routers and switches
- Serial communication with many devices such as GPS devices
- Serial terminals on devices like the Raspberry Pi

DTR: Data Terminal Ready - an output used for flow control
RX: Serial data Receive pin
TX: Serial data Transmit pin
VCC: Positive voltage output - this is controlled by the jumper. If the jumper is set to 5V, this will provide a 5V output. If the jumper is set to 3.3V, this will provide a 3.3V output.
CTS: Clear To Send - an input used for flow control
GND: Ground or 0V

For most uses, you can simply connect the following pins:
RX on this board to the TX pin on your device
TX on this board to the RX pin on your device
GND on this board to GND on your device
