    Under $20 on Amazon, why $35 here ????

    I would go a step further and say that the AVR is a low end micro controller and it is a entry point to the world of embedded systems. While I agree that the AVR series is great the ATmega328 is pretty limited with only 32K prog/2K ram and limited peripherals @ 8/16MHz. This is 2011 there are dozens of ARM Cortex-M3 processors with 3+ UARTs, SPI, I2C, Ethernet, USB, SDIO, external busses etc.. and runs @100MHz for about the same price or a little more and about the same price for a finished board. Why is everyone tring to cram thier latest creation into an old 8bit processor when it could easily be done on a 32bit processor.
    The AVR is fine for simple tasks but for complex systems like this why not use a modern processor?

    You do realize that a viewer could just print out a picture of the product and wouldn’t need to buy one??? just add scotch tape!

  • Product DEV-10748 | about 3 years ago

    What are the old and new part numbers? so I can check the datasheets and see what is different and if it applies to my application.
    Thanks in advance.

    What part was the old part and which part is the new one, the schematic has a generic part number. What is the difference between the old and the new???
    I just bought the old, so I can only assume that the new one is significantly better.

    Kinda a waste of offering this as a BGA even if it was leaded 2mm is smaller package than most could handle, adding BGA means no one should buy this.

    I don’t really get the bus mode its is 6pins (4 enables, direction and step) vs standard 8pins(4 direction and 4 step). If you only have six pins available, it helps but 6 vs 8 is a minor difference and allows 4axis simultaneous movement which seems like a much bigger plus. I’m surprised that the A4983 are used here as the A4988 are the newer parts with a couple of protection features added.
    The A4983 is capable of 2A but this only true when a heatsink is added, without a heatsink these chips will overheat with anything over 1 A.

No public wish lists :(
