Programming the Arduino Pro Mini

Hi,

I’m about to buy a Arduino Pro Mini, but am confused as to whether I need extra hardware to download sketches to it.

This quote from http://www.arduino.cc/en/Guide/ArduinoProMini suggests I do need extra hardware……

The board comes without built-in USB circuitry, so an off-board USB-to-TTL serial convertor must be used to upload sketches.

But this quote from http://arduino.cc/en/Main/ArduinoBoardProMini suggests I don’t need extra hardware.....

The ATmega168 on the Arduino Pro Mini comes preburned with a bootloader that allows you to upload new code to it without the use of an external hardware programmer.

If I do need extra hardware, I assume either of these http://arduino.cc/en/Main/USBSerial or http://arduino.cc/en/Main/MiniUSB will do ??

Any clarification would be much appreciated.

Thanks

You do need something more than the Pro Mini itself. There is no way to connect the Pro Mini itself to the PC for programming.

The quote refers to using another Arduino to program the Pro Mini. In my mind, that's external hardware. Possibly something you already have, as opposed to something you need to buy, but external nonetheless.

If I do need extra hardware, I assume either of these http://arduino.cc/en/Main/USBSerial or http://arduino.cc/en/Main/MiniUSB will do ??

They should.

Thanks PaulS,

Tell me about it. I bought a $180 wheel for sharpening my lathe tools, only to find out it doesn't fit my grinder. Now, I can't find a grinder with a long enough shaft to accept the wheel.
