  • Not sure how accurate this actually is but it has 0.001 resolution on the readout. Seems to be fairly accurate to me.

  • Digital calipers have finally come down to a price that hobbyists can enjoy! Free shipping too! And even product Specs!!!

    Seriously Sparkfun, even if I respect your commerce, it’s incredible to sell this no-name digital caliper 30$ since you can have it ebay for 10$ including shipping.
    For this price, you should at least post the product specs, a video about it’s precision and send some cookies with it.

    • Point taken. We’re looking for a cheaper supplier. Essentially, they are all the same caliper really.

  • Do you sell a cable for this caliper to interface with my computer? If not do you know where I could buy the connector that plugs into the Caliper data port?
    Thanks,

  • These seem to be the usual cheap (chinese?) calipers - the on/off button on these just blanks the screen. I have checked this with an ammeter. (9.7uA when on in mm mode/10uA when on in inches mode/9.0uA when off all at a Vbat of 1.34V)
    I can also confirm that these calipers are not compatible with the “hidden” extra modes - connecting any pins on the connector at the top doesn’t do anything (apart from 1 and 4 which shorts out the battery).
    However they seem to be very accurate - at least in mm mode - checked against a pair of (borrowed) calibrated dial calipers and they seem to be perfect to 0.01 of a mm.
    That said they are a welcome addition to my tool kit and I can now return my mates calipers to him…

  • ThinkGeek sells a more advanced version of these (can display fractions instead of decimal points) for $14.99: Stainless Steel Digital Calipers

  • Just a heads up for anyone who has purchased these calipers or is looking to purchase them. I don’t know if this will work with these or not, but Hack a Day just posted a great article about how to unlock hidden features of cheap digital calipers that look suspiciously similar to these.
    Apparently by shorting pins in the data port, you can increase the refresh rate and enable min/max/hold features.

    I haven’t had a chance to try this as all of my measuring equipment is Mitutoyo, but I’m guessing most of these cheap calipers' electronics are made in the same plant…worth a try anyway!

  • These are really decent calipers. I bought them on Amazon for about half the price as they are listed here, but I wish I’d gotten them here instead so I could support the local peeps. At this price they are a steel.
    I tested this against some analog feelers, and mine was dead nuts…China is doin good!

  • I have the 8" version. Made in China (as most things are), but very nice.
    Mine is 0.0005" (0.01mm) resolution, and looks identical to this, so I’d imagine this one is probably the same.

  • plleease try to get these back in stock. a pair of digital calipers would be really nice right about now, and these are the best i’ve seen for my money

    • We have an extremely rough ETA by the end of this month. Hopefully we will see them by then.

  • Looks like this had a uart port on it?

  • Is it made in USA?

  • Is there a spec sheet or manufacturer part number I can get?
    How accurate is this?
    Thanks,
    Dan
