STK500 is what you need. You can buy it from Digikey.

            I have a project (Signals for a 7.5” gauge railroad) that I need to get up and running quickly.



I am working on the design of a custom board based on an ATMEGAxxx to support a wide range of functionality but I do not have time to layout and produce the boards (Eagle, toner transfer, etch, stuff) I need for a minimal system up and running in the time I have.



What I’m looking for is an inexpensive prototyping board (in the USA) that I can get to support my initial requirements.  I figure I’ll need 8-10 of them.



Initial requirements:



1 ATMEGAxxx processor (ATMEGA168 desired, but about any AVR that supports the functions below would work).

2 JTAG support (for breakpoint debugging, loading, etc.)

3 At least 3 digital I/O

4 At least one PWM output

5 At least one analog input

6 On-board regulator



Desirable extras:

- RS-485 I/O (or serial pins to wire a Maxim RS-485 chip to)

- Additional digital I/O (up to 16), analog inputs (up to 3)

- On-board drivers for the digital I/O capable of sinking 10-15 ma (driving 10 mm LEDs)

- Did I mention inexpensive ☺ …



I know that there are many more parameters you need/would like to know but, without getting into an extended description, that’s the basics.

 

Cheers,



Chuck Hackett
