I want to build my Arduino UNO clone.
QuoteI want to build my Arduino UNO clone. No!You want to build http://arduino.cc/en/Main/arduinoBoardDuemilanove
...Can someone tell me why he should build either of those (as opposed to a garden variety UNO) ?
Do I have to read all the spec for the Duelmilanove to understand why you guys recommended that one ? What's special about that?
or inside the USB shell on a nice long cable
I use a Sparkfun FTDI BASIC for my 3.3V Pro-Mini, 5V Pro-Mini and breadboarded ATmega328 chips. It works great. no problems.
i am always amazed at the number of people who still like to put that usb/tll converter on every board. talk about redundancy.
...admittedly nice being able to plug in a new chip on those big socketed boards but pro-mini is so cheap at $2-$3 shipped dollars its almost not worth it.
It's a good point but the sub-$3 range is for the China variety of the clone. These clones often have varying pinouts, especially around the Vcc/Gnd area of the board. So caution needs to be utilized and the realization that one board ordered today may differ from one board ordered two months ago.
The other issue, which should be considered, is the need to have a soldering iron and decent skills in using said iron. Even if you just need to solder the headers for breadboard use. Soldering and unsoldering wires to the little boards will eventually cause copper foil lift at which time the board.
It is a cheap and viable solution, but not one that I would recommend for the "My First Arduino" award.
My last shipment of 5 Pro Micros and 2 dead units... one was revived with reflashing the bootloader for the 32U4 but one is eternally dead. The previous 10 Pro Micros were 100%. 2 duds out of 15 may be an unacceptable rate of failure and most newbies will be unable to flash the 32U4: something to think about.
