BoArduino and ZIF sockets

[chassmith]

Would a 28 pin ZIF socket fit on the BoArduino? Or are the clearances just too tight?

you could try this

dunno if it would work tho

Actually, I picked a couple up from Evil Mad Scientists a few months ago. I was just wondering if anyone had tried it before. I guess I get to be the guinea pig. I'll let you know how it goes.

Thanks,
Chas

• Use an ordinary DIP socket on the board and install the ZIF in the DIP socket. This will raise the ZIF socket above the surrounding components.
• Install the resonator and LED parallel to the board.
• Use 1/8 watt resistors - they will fit horizontally.

It's safe to use 1/8 W resistors?

[adafruit]

yup

ZIF sockets usually have pins that won't fit in standard sockets. What I've done to make them work is get DIP component headers with thin, flat, "Y"-shaped contacts (with the vertical part of the "Y" going through the plastic). The lower part of the contact mates nicely with standard side-wipe DIP sockets, and the upper part fits well with the "transverse" pins on most ZIF sockets.

no, I'm the pig around here. oh wait, that didn't come out right...

I just tried and it works fine. I have the EMS board (his black proto board) and also the zif socket he sells.

note, its a fake knockoff socket, its NOT the textool socket but if you look closely, you'll see :TFXTDOL.

man, fakers.... but the socket does work - its just a knockoff socket and not the name brand one you might have thought you were getting.

Fine that your knockoff TFXTDOL socket works, but not so for mine. I just built an AVR ISP Shield Kit and it came with one of these crappy knock-offs. I know it's not a great photo, but if you look at pins 1, 14 and 15 you can see that the spring tab does not open all the way when the lever is released, creating a risk of the chip not seating properly. What's most annoying about this is I just finished assembling this puppy, never figured to actually inspect or test out the device beforehand because as we all know, TEXTOOL is a quality product, one that I've been using for decades. I'm really not looking forward to solder-sucking 28 pins to get it back out. Bah!

hi matt,

thanks for posting up, you also emailed us at support@adafruit.com so we'll follow up there.

thanks,

Hi Matt,
I see you have connected the Piezo beeper on your shield. Where did you determine which pins to connect it to? I could not find that detail in the tutorial (which is great by the way!)

There are two tutorials. You want the "Standalone Programmers" one: http://ladyada.net/library/tools/standaloneisp.html

We also soldered in a Piezo beeper, to give us feedback. One side is soldered into Analog 3 the other side is soldered to the ground rail right next to the analog breakouts.

Hi Adafruit-
Thank you - I don't know how I missed that.
Thanks again,
duckie
