Atmel AVR ISP pinout (AVRISP, JTAG ICE MkII)


So, you lucky soul, you have a Atmel JTAG ICE Mk II, AVR Dragon, or an AVRISP MkII on the bench.

Can't remember the pinout for the AVRISP port? Or the color codes on the squid cable?

Me either. Here's a reference guide to help you.

AVRISP Pinout

Here's the AVRISP pinout diagram for both the 6-pin and 10-pin AVRISP header.

This diagram shows AVRISP pinout diagram for programming ATtiny2313, ATtiny2313A, ATtiny4313 AVR microcontrollers.

ATtiny84 AVRISP pinout

ATtiny85, ATtiny13

Here's a pinout diagram for an 8-DIP ATtiny11, ATtiny12, ATtiny13, ATtiny13A, ATtiny25, ATtiny45, ATtiny85:

eeZee Tiny Breakout Boards

eeZee Tiny makes it easy to prototype and program your ATtiny

My eeZee Tiny breakout boards include AVR ISP headers so you don't have to remember the pinouts above. They're low cost and available from my store on Tindie.

If you think others might benefit from this article, could you do me a favor and share it? Thanks!
