Programming an Arduino Pro or Pro Mini

The CY7C65213 chip can be used to program an Arduino Pro or Pro Mini, just like SparkFun's other FTDI-based USB to UART chips. As a basic example for getting started with this board, we will be demonstrating this hardware connection.

Note that, unlike the other boards, you'll need to buy some kind of header to interface to the Arduino board, as no header comes pre-soldered to the CY7C65213 breakout. This affords you the option to choose the connector that best suits your purpose or to solder wires directly between the two boards.

Don't Forget! Double check that the VIO Selection Jumper is set to the appropriate voltage level for the board you are connecting to (5V/3.3V). If you are connecting to a board with a different reference voltage, remove all solder from this jumper before powering up your circuit.

Once the board is connected and the driver is installed (which should happen automatically on all major operating systems), no other changes are needed for the board to be used as a programming connection. Simply select the COM or TTY port in the Arduino software and proceed as normal.
