    I am building 3 devices and each of them needs an Arduino as its brains. I am about to order parts so pls tell me if the following strategy is the right one?

    I am doing the development on board A (see pic below), its the usual arduino uno board with USB interface to download programs from PC

    B- I will order 3 of these boards as there are 3 products to build

    C- To download the program to each board B from the PC I will order 1 board C
    Once the program is downloaded and it works I will remove the board C

    Is that the way to go or am I missing something here?

    It is some applications. That allow the Arduino unit it self to be AVR controller programmer. This page may give you some ideas http://electronics.stackexchange.co...use-an-arduino-uno-as-an-atmega328-programmer
    The point is to first download the Arduino bootloader into a blank chip. Then program it with whatever you have made with the Arduino system. After that the controller should work OK with only correct power and a correctly connected 16 MHz crystal. I am not Arduino user my self. So I might be wrong here

    I've had mixed success with USB to serial converters. Personally, I'd use an older computer with a serial port and forget the converter. It may however work fine, let us know.

    What you propose looks fine to me, I've had no problems with FTDI/serial converters.
