Description: Your basic SOIC break out boards. What’s the difference? The 8 Pin board is TINY. And you can’t beat the price! These are custom PCB boards that interface standard JEDEC SOIC devices to standard .1" headers.

This board has a standard SOIC-8 footprint with a layout that fits all standard JEDEC SOIC-8 devices.

40 Pin break-away headers are perfect for use with these custom PCBs. Machine pin headers may be a better option for IC sockets.

Customer Comments

  • I have to agree with the other comments, the pads on this could be MUCH longer. Even when I bent the chip’s pins inwards, the pins sat right on the furthest extremities of the pads.

    If Sparkfun is designing these, they -really- need to manually lengthen the pads, and then introduce it as a new part (If I know it’s redesigned, I’ll give it another chance, but right now I will try someone else’s adapter instead).

  • make sure you check the SOIC-8 you are planning to solder to these before you buy them!..if the pads had been made a bit longer on the soic layout then they could have been used for more “SOIC-8” packages….threw the Sparkfun ones in the trash and bought some from a different vendor that have a better layout for less.

  • The second I touched the pads with soldering iron 3 pulled right off, I used temp controlled soldering Iron on only 280 degrees and I was very careful I would not recommend this board I ended up using wire wrap to complete connections because the darn pads for the smt pulled right off

  • “SOIC” here refers to the JEDEC SOIC package whose body is 3.8mm wide, unlike the EIAJ which looks similar but is actually 5.3mm wide. Some more details here (which I should have read before buying):

    • Good catch xxv. I just made the same mistake and then saw your comment. The product description is now changed.

  • I know of an excellent application for this board. Sparkfun you guys should look into making up a batch using this board and the DS2482-100 which is an I2C to One-Wire translation device.

    Making these up, using those chips and this board requires an exacting talent, and steady hands, and good tools. I think I’ve got all of that, but I believe all of you have the tools to do the job and better.

  • Will this work for what TI is calling their “narrow SOIC” package? I need to experiment with some Low Voltage OP amps in this case LME49721, and i can’t imagine doing so without the ease of whit boarding. The TI data sheet for this chip at but I don’t see any reference to whether or not is “JEDEC SOIC”.

    • There’s no datasheet / eagle files listed on this page, but from measuring pixels I’d say you should be fine. The ‘narrow’ SOIC is actually the typical SOIC. There’s also a wide body SOIC for which the pads on this might be a bit too short though I’d bet you could still solder one of those on, too.

  • Has anyone used this as a breakout for the Lassen IQ? The connector has a pitch of 0.5", but i’m not sure of the width.

  • Hi,
    can this be used for TSL230RD
    A little help appreciated

  • Got two of these for quick BIOS swapping. Of note:
    1. SIZE (See the earlier comments by xxv and Member63167). To re-cap: the pitch for the SOIC lands is the standard 1.27mm, but their complete lead-to-lead width (outside edge pin1 to outside edge pin8) is only 7.45mm. As luck would have it, my chips turned out to be the EIAJ “wide/extended” format, so I had to crush the pins inward with a pair of pliers to have them all connect. I understand that the small size is a feature of this board, but it could be made properly compatible with EIAJ chips with a width increase of 2mm or less. The Wikipedia link xxv posted got eaten by the site, the following one is working: SOIC specs @ Wikipedia
    2. The pads did not seem to want to make a very good connection even though I pre-tinned them (using standard 63/37 solder)
    3. Several of the pads did lift of the PCB during soldering, but none actually broke. Probably not helped by extended heating, due to #1, #2 and the use of a cheap uncontrolled 35W iron.

  • The dimensions in the text do not seem to match the images. The text says it is .78" long and the image shows over 1". Which is correct? Thank you.

    • Look at the image again, the image is cut off before it ever gets to 1". Those are centimeters you’re seeing.
      It’s a little over 1 and ½ cm long and a little over 1 cm wide, or .78" long and .5" wide.

  • I purchased several of these to fan out a Numonyx M25P16 serial flash memory. I did not experience any problems as the previous user did. I would recommend these to someone considering them.

  • No eagle file available?

  • The holes for the header on the board I purchased from sparkfun are too small for some square post headers. Purchase their breakaway headers or machine pin headers for a proper fit, or use straight pins and cut off thier excess length.

cost too much, and no pins

They cost about 3 times what I expected to pay, and then I had to go out and buy pins so that I could insert the adapter into my prototyping board.

very good

This is a good PCB, good quality and clean. This PCB would be smaller and works better for me if the SOIC footprint moves in between the DIP foot print. Thanks, Ron
