arduino choices?

I'm new to the arduino world and I still haven't even bought my first arduino board yet, so before making a purchase i was wondering if there were any real big differences between all the different kinds?

I'm planning to use the PWM outputs to run an H-bridge circuit to control a motor to spin bidirectionally, and was wondering which board would be the best for this job?

thank you!

You are going to build the arduino into something? Program it & leave it there? I'd go with something that uses a DIP part that you can easily replace when you blow it up. Seperate USB/Serial adapter so you can download sketch & disconnect and not blow that up while testing. Do you need a voltage regulator? Are you in the US? RBBB from Moderndevice.com http://shop.moderndevice.com/products/rbbb-kit or build one up from this http://store.nkcelectronics.com/arduino-runtime-board-rev-b.html

Or build one up from a Mini-uino with surface mount parts if you're adventurous, see the link in my signature. (I need to order more, 3 week lead time if you're interested, the last 2 of the original 50 PCBs that I purchased are committed).

There’s scores of choices once you go looking. Main differences I see are what ATmega, what USB chip and size.
==>> The big differences are what shields you might add and those will plug on the standard-factor boards.

But I like my UNO.

I’ve been window-shopping lately at dot-coms Adafruit, Seeedstudio, and Arduino-direct. All affordable.

I do agree with Crossroads. Arduino is for programming and prototyping, the final should cost less.

These show how to shrink a project onto an 8-pin ATmega but you can use a bigger chip instead:

Maximum size of program, SRAM, EEPROM memory and number of I/O pins and internal hardware peripherals is the main difference between the boards. All are useful. Best to start with the standard Uno board unless you have specific application requirement it can’t meet. If you are successful in your Arduino journey you will end up with several types of boards in time.

The basic Uno board will do fine for that.
thank you!
