10-pin cable pinout

by eli2k on Sun Jul 26, 2009 6:16 pm

I put together USBtinyISP from the kit, and the 10-pin cable came assembled. I was wondering how I can figure out the pin-out of connector? I want to connect it to an AVR-breakout board from Sparkfun, but I don't know what is the correct way to plug it in, or a method I could test in the future to figure it out.

Thanks,
- Eli

the 10 pin connector is 'standard 10-pin ISP' and works with any 10-pin avr header that is for ISP (not jtag)
red is pin 1 - which is standard as well

I was looking more for something like this: http://andersonmicro.com/wp-content/upl ... pinout.png

That's for a 6-pin, but I'm trying to find a 10-pin. It looks like what I have is working when I plugged the 10-pin cable in, so maybe I'll just take a picture and label it myself for future reference. :)

AVR ISP 10-pin header pinout:

Pin 1 -- MOSI
Pin 2 -- Vcc
Pin 3 -- No Connection
Pin 4 -- gnd
Pin 5 -- RESET
Pin 6 -- gnd
Pin 7 -- SCK
Pin 8 -- gnd
Pin 9 -- MISO
Pin 10 -- gnd

Hope this helps
John

oPossum's image did it for me; so if I know the red wire is pin1 and it's always in the proper orientation, I should be able to figure out the other pins. :D

That image is from page 5 of Atmel's app note AVR042: AVR Hardware Design Considerations
