    I needed a timer to switch computer ON/OFF, with ability to send a few seconds pulse rather than simply switching on or off, and to have a full calendar so that I could allow exceptions for a few days on the year. This module give it all, with addition of the micro sd card reader, my client can simply modify the values on his computer, slide the card and update the variables of the program.
    The code samples really provides most of the snippets you would need and in just half a day, I had all coded and ready to ship.
    The board and assembly are flawless, a bit more compact design would be better but the unit is by no mean “bulky” especially when compared to similar featured programmable timers.
    I didn’t use the usb serial more than for programming and I would welcome a simpler version without usb interface but just a serial plug on which you could put a ftdi USB serial cable.
    Out of curiosity I checked the code snippets for linking to a computer and it seems pretty good too.
    All in all, it does the job, quite simple and effective, I like it and will use it again.
