Solderless breadboard with 2mm grid spacing...

jcpole · 2006-02-11 22:15

Hi all...

Does anyone know a source for solderless breadboards with a 2mm grid spacing? Does such an animal even exist? I just picked up a bunch of components with mounts that require that spacing, and I really don't want to solder them to anything just yet. I know that the 2mm grid is primarily for production, but I'm wondering if I can prototype with it as well. If there are no 2mm grid solderless breadboards, does anyone know of adapters that can convert 2mm pins to a regular .1 grid solderless breadboard?

Thanks...

Jamie

Jamie,
I asked a similar question a while back, not about a breadboard, but an adapter. See the discussion here:

Paul Baker gave help which worked perfectly for a particular adapter for my project. I have found somewhere 2mm breadboards, but I'll have to look again.

Thanks for the info - for some reason, my searches didn't find that thread.

I think our requirements are similar, so any information that you have would be very helpful. The components & modules that I'm trying to work with seem to be very delicate, so I REALLY don't want to solder them without working through a prototype first.

Found at least one source of breadboards with 2mm spacing. Still doesn't help you with the translation though, I'm afraid;

I think they are maybe more common across the pond....

SOLDERLESS breadboard for 2mm -- no dice.· You'll have to look for some breakout boards that convert to 0.1in SIP and DIP spacing (you'll have to solder/mount·the ICs to the boards.)

jcpole · 2006-02-12 01:28

Jim:

Thanks for that info - I'm really looking for solderless boards, but if push comes to shove, I might just buy that board and mount one of the sockets with wire leads that I can plug into a standard solderless breadboard.

Thinking about the mechanics involved with creating a solderless board with a grid that small, I'm not even sure that it's possible.

PJ:

Thanks for the response - I'm trying to find an appropriate breakout board now... A 2mm solderless board sounded too good to be true to me as well.

· I know that ( www.sparkfun.com )·has some breakout boards and "surfboards" are available from a number of hobbyist suppliers ( www.alltronics.com·), but they're for SOIC (-8, -16, etc.)

· For what it's worth, Sparkfun has (had?) an interesting account of their experiences with "wave soldering" --·where they finally used a wal-mart electric skillet with what they regarded as very-good/excellent results.· Go figure.

Breadboards are standardized at .1" spacing because of the dip package. What is the specifics of the package you are trying to accomodate? I already have someone else in a queue for a ZigBee adapter module (he wants me to mount it as well, so Ive held off designing it to get a bundle of boards manufacturered at the same time). Assuming its about the complexity of Jim's board, and you'll do the submittal and mounting yourself, I could probably do it in about a week (Im heading to Parallax later this week and I have loose ends (like V-day and what not) to take care of before I leave, so I cannot promise anything before I return).

My application requires an interface with 20 pins (2 rows of 10 with 2mm center pin spacing).· Some kind of breakout that allowed me to plug the module into a standard breadboard (just like a DIP) would be ideal.· I only need 1 of these for prototyping/testing at the moment.

Thanks...

What is the spacing between the two rows of 10-2mm spaced pins? Is it 22mm?

The spacing between rows is also 2mm.

Thanks.

So its basically a 2x10 (dual row 10 position) 2mm header then? I should be able to mod Jim's board for your use quite easily.

Exactly - that's all it is.

Jamie, Paul:
BTW, I used the SparkFun service and was quite happy with the product. If you don't need immediate service, they are quite reasonably priced. Took ~3 weeks I think, submitting Paul's drawing package. Recommended.
Again, if you want one Paul, happy to send one along...

Here you go Jamie, the explanation for Jim's board is the same here, only I moved the 0.1" headers out to .5" to accomodate the 2mm package inside. Using sparkfun's service will be $12.50 all costs included. Pickup some of thier machine pin headers if you want an easy fit into a breadboard, but the standard square post headers will also work with more insertion and extraction force, the 2mm sockets should be availible from digikey.

If you want to check the layers yourself, Viewmate is a free program to view gerber data. Let me know if there are any problems.

Jim: While I eventually want to experiment with Zigbee, its not a priority, so the board would just sit around. Besides when I do get to it Ill need two modules to communicate, but thanks for the offer.

Another quick question - SparkFun is asking which program created the design.· How should I answer this?

Thanks...

So, I have the Onion Omega 2 with, of all things, 2mm spacing on the pins.

Since this is my top search result for 2mm breadboard (which doesn't seem to be a thing yet), I am commenting my solution that is a little janky.

I bought 2mm female to 2.54mm male jumper wires. $8, everything is removable and reusable including the breadboards I already have.

Duane Degn · 2017-01-22 19:56

I have a few 2mm parts I wanted to use with .1" pitched breadboards and perf-board so I'm having a few adapter boards made.

I've attached the Gerber files.

Anyone can submit these zip files to OSH Park and have some made.

The ten position strip has a small protrusion to make it meet OSH Park's 0.25" minimum width requirement.

2mm headers are available from lots of sellers online.
