Hi all,
I found a schematic about a AVR development board and modified it with a 8 pin socket. Im a newby with electronics so i hoped somebody could tell me if this could work and if it doesn't were i made a mistake.
Hope to get a respond!

Hard to read, but it looks good besides the crystal caps. Way too big, you need something more like 10-20pF typically.
Yes i noticed that after i uploaded it i am going to use 22 pF caps for that. Thanks for you're respond!
What shall i do with the AREF pin? Just leave it open? Connect it to the ground with an 100nF cap? Ore connect it to the vcc like the schematic?
Tie it to VCC and probably put a cap on it as well.
Hi Gurinder,
The led is just a power indicator. I don't see why i would replace it for an RGB led. Ofcourse i can try to control an RGB led with my development board!
@steve , ohh , I missed that , Yeah I meant an RGB Led connected to GPIO , so you can easily test the board.
I will definatly try that!
Hi everyone,
Here is my version of the AVR development board that I made. It consists of AVRISPMKII programmer, Power Board which supplies 5V to the target chip for programming, ATtiny Adapter Board, ATmega 28 Pin Adapter Board and a wall wart power supply (not shown).
I went with a modular approach where you can program various Atmel chips by making chip specific adapter boards.
I have tested and verified the adapter boards work properly.
If any one is interested in my design I will supply the art work and part list needed to make the AVR development Boards.
Let me know..
Thanks

That's a cool setup!
