    Hi,

    Just ordered my ACF from Adafruit, which shipped today. Psyched!
    Im my haste to order however, I did NOT order the suggested USB/FTDI cable (https://www.adafruit.com/products/70)
    Oops!
    Will an alternate FTDI cable work??
    a) I have the “FTDI Friend” (https://www.adafruit.com/products/284)? I have that.
    b) I also have the simpler USB/TTL adapter: https://www.adafruit.com/products/954
    If you tell me that one of these cables will work, I will relax and wait for my delivery. 
    Otherwise I’ll place another order and get the correct FTDI cable.
    cheers,
    Scott

    The FTDI friend (a) will work, but the simpler USB/TTL adapter (b) will not work. As it says there, “This cable is not good for Arduino re-programming.”

    I just received an A5 from Adafruit a couple of days ago; it came with version 1 firmware.  If you want to install new firmware, be sure you read the instructions about changing the baud rate (in the Sanguino boards.txt file), since the v1 bootloader runs at a lower speed.

    To replace the bootloader, I used a USB Tiny, which worked perfectly.
