    There doesn’t appear to be an official OS X driver. There’s an unofficial one at https://www.mac-usb-serial.com/ but it costs 7x the price of the device….

    Works absolutely great for the price! Remember to download the recommended driver via http://www.wch.cn/download/CH341SER_EXE.html
    and consider to press the reset button while uploading your program.

    Works like a charme. (Don’t forget to use the driver ‘njnazim’ desribed) I have replaced te 6-pin single-row male connector by a 2×6-pin double-row connector. I wired DTR and other signals to the second row. Now I get the ‘automatic reset’ like on the original FDTI board. Really a nice little board. Using it for programming Mini Pro and others.
