New product request from Parallax

Erik Arendall

I would like to see Parallax release a production programmer for the BS2 with a ZIF socket. I think that it would be a good idea for projects that use the BS2 in high numbers.

What is everybody else's opition on this?

Erik,

Could you put a ZIF socket into a BS2 Carrier Board and add a wall-pack power supply? This could solve your problem for about $35.00. Or, do you want a more formal-looking design? Part of the challenge we face is that what appears to be a simple design still costs several thousand to get started in inventory and design, adding stock codes, etc. And if the volume is low, such as it would be in the case, the cost for our customers would be high.

I made my own board with a zif socket i picked up for about 14$ from HVW tech. Many companies sell zif sockets and·it is·much more fun to make·a dev board according to your own needs.

Jameco sell a 24 pin ZIF for $7.49, these are nice because they allow you to use a narrow or wide 24 pin device in them.

This is true I never though of using a ZIF Socket and a carrier board. You could also use an adapter on a BOE.
I was looking for a functional design, more over a formal design. I understand the cost and invintory side, i work for a large company that has to deal with the same thing.

Thanks for the ideas guys, i will put them to good use.

I have ZIFs and they are useful, very useful for a lot of swaping and programing.

Nonetheless, you may find that the board that you originally thought was ideal for the ZIF is the wrong one.
So, it is best to just buy a ZIF and set it up so that it can plug into any board.

I did this by mounting the ZIF to a small ciruit board and mounting longer pins that extend through the backside and make it into a usable plug-in.

The trick is to buy a circuit board that allows you to mount components on both sides as you first have to solder the pins in place and then turn it over and mount the ZIF.

The reason for going to all this trouble is because the pins on the ZIF will not plug into a normal IC socket AND the ZIFs are quite pricey.

After you have built your plug-able ZIF, you may worry that those pins are too big for some motherboard sockets [noparse][[/noparse]I did]. IN THAT case, I first plug the ZIF into a cheap, throw-away IC socket and then plug the IC socket into the motherboard's socket. In this way, the cheap, throw-away is the socket that gets streached and bent - neither the ZIF nor the motherboard suffers.

This part can also be plugged directly into the socket, so you don't have to modify your carrier board.

If you want to connect a zif socket to the existing socket on the carrier board you'll need to use 12 pin headers on each side to raise it above the components.· It works great, we use it for testing stamps.
