Frequently asked questions
How do I wire it to a microcontroller board?
Cross the data lines: connect the cable's TX to the board's RX, and its RX to the board's TX. Connect GND to GND. Check the pin labels on the 4-pin header before connecting power.
Does it need a driver?
The listing states support for Windows XP, 7 and 8, Linux and Mac. On some systems the PL2303 driver must be installed before the port is recognized.
