Hardware Question 1.27 to 2.54 pitch conversion

wdfreemanjr

Hello,

I purchased an RF module that is a 15mm x 15mm square with 1.27 pitch SMT pads . It is made to solder directly to a PCB board, but for prototyping purposes, I need some sort of little holder that this will snap into and expose the pads as pins that can be inserted into a standard solderless breadboard (2.54mm pitch). Has anyone ever heard of such a thing ? Any and all suggestions / alternatives welcome.

Thank you in advance and I apologize if this is the wrong forum.

I have attached an image of the module.

The 15mm width poses a challenge. What you could try is to get a 24- or 28-pin SOIC-to-DIP adapter, saw it down the middle, and solder each half to your module while the two halves are plugged into a solderless breadboard. Here's a source for the adapters:

Standard IDC ribbon cable has a pitch of 1.27mm. You can solder one end to the module's 11 adjacent pins, and use 1 or two male 12/14 way IDC 0.1" DIL plugs at the other end to plug into the breadboard.

Using 2 DIL headers spaced 0.3" apart allows you to plug "odd numbered" connection pins to the top half of the breadboard, and "even numbered" pins to the bottom half of the breadboard.

Also, I like what Andy and/or Thomas have done with the back of the upcoming PropBOE. Unfortunately its probably only slightly too wide for your module, but there are plenty it will be really useful for.
