AVR Microcontroller - Dev Board
« on: June 09, 2008, 11:44:14 AM »
I'm looking for an Evaluation Board mounting Atmel Microconttoller.

Preferred features:
- new microcontroller
- ADC, DAC
- Servo support and H-Bridge
- Many generic I/O
- USB programming, supported by Atmel development tools
- RS-232 would be fun
- costs around $50 + s&h

I like this: http://www.digilentinc.com/Products/Detail.cfm?Prod=CEREBOT-II&Nav1=Products&Nav2=Embedded
but I dont want to spend 40$ for the JTAG usb cable and I dont want to use a second software (the first should be used to write the code and compile) just to program the board.

any suggestion? online shops links are welcome.

I can't believe you all guys build your own  development boards :P

if you don't ave Atmel, what kind of microcontroller do you use?

If you have a decent knowledge of electronics, making your own board is a good choice. You'll learn much by doing so.... You need to decide wether or not you're ready for it.

There are two big producers of microcontrollers (for robotics atleast):
Microchip PIC or Atmel AVR.

They are both good choices, and before you ask, there is no "best one". read the FAQ

I do have a decent knowledge of electronic, but I don't have any time to project a nice dev board. I've done in the past for pic and I'm doing now for msp430, but I would like to have something done from Atmel... any suggestion?

what about Arduino and Picaxe?

Arduino is a very good choice.
If you want a more advanced board with more functions you should look into the Axon.

in teh first place i dont know why you are after a Dev board,, whats wrong with the micrcontroller alone?
somthing like the atmega128

all of these are already in the atmega128
exept the usb port and the h-bridge

There aren't many boards that have a DAC . . . are you sure you need one? You can also make one with a PWM signal, a resistor, and a capacitor.

Also, why not USB instead of rs232? :P

As for the H-bridge, if it doesn't come with one built in, you can always buy one you like separately. This is why I didn't include a motor driver with the Axon . . .
